However, Chen Muwu does not intend to and does not need to preemptively publish the results of Raman scattering experiments to win the Nobel Prize in Physics, because he now has a theory of gamma ray scattering.

When Capitsa and Blackett managed to catch the traces of the recoil electron in the cloud room, it would be even more certain that he would win the prize.

It is estimated that in 1927 at the latest, Chen Muwu will be able to win his first Nobel Prize in physics.

As long as he can win the prize before 1927, Chen Muwu will surpass Lawrence Prague to become the youngest Nobel laureate in history, and this record will be maintained until more than 80 years later.

Of course, it was not the younger, more gifted physicists who broke this record, but the increasingly politically correct Peace Prize jury, which was selected by their increasingly deformed and deformed jury.

……

There has been a public case in history about who first discovered Raman scattering.

Raman submitted his final paper on February 28, 1928, and the week before, on February 21, two Surian physicists, Landsberg and Mandelstein, were the first to independently submit a paper on the phenomenon in a domestic physics journal.

But in the end, Western academics, who have the right to speak, prefer to name this scattered phenomenon after their colony Indians, rather than after people from red countries with similar skin tones and appearances.

However, in Sulian, this scattering phenomenon is called "joint scattering" because it was discovered by physicists together.

To a certain extent, this designation also indirectly affected our country, and in the early physics papers after the founding of the People's Republic of China, the term "joint scattering" appeared much more frequently than the "Raman effect".

Similar to the previous Compton effect, the Raman effect is an energy exchange between the incident light and the molecules, which in turn changes the wavelength of the scattered light.

Slightly different from the Compton effect, it is the molecule that collides with the photon this time, not the free electrons in the Compton scattering.

To a certain extent, the Raman effect can also confirm the reliability of the optical quantum theory, which is also in line with Chen Muwu's previous papers in terms of academic logic.

So since he thought of the Raman effect on the ship, Chen Muwu decided to make it his first experiment after arriving in Cambridge.

……

In fact, Chen Muwu was not saving money for the Cavendish laboratory, he also wanted to ask Rutherford for equipment, because in the university laboratory at that time, the light source he used to do Raman scattering was a laser with strong monochromaticity and high collimation.

But in 1923, even if Chen Muwu ran to all corners of the world, he would never find a laser.

Although Albert Einstein proposed the concept of "stimulated radiation" as early as 1917, the first laser beam produced by humans based on this principle was not until a few decades later, in 1960.

Chen Muwu felt that he didn't need to develop a laser decades in advance for the sake of a Raman scattering.

If you want to develop a laser, there is still a lot of preliminary work to be done, such as first proposing the wave equation (Dirac equation) under relativistic effects.

But before this equation can be developed, we must first understand Heisenberg's matrix and Schrödinger's equation, Pauli's principle of incompatibility, and the discovery of the spin of electrons, and so on.

The meal should be eaten one bite at a time, and the road should be taken step by step.

It's not realistic to ask him to rub a ruby laser out of his hand now, isn't it?

So after the Duke of York got married, all the physicists went to London, and in the few days when he was not in the laboratory, Chen Muwu walked around Cavendish to find a high-pressure mercury lamp that could be used.

He thought that without a laser, he could barely carry out experiments by splitting a beam of light from a mercury lamp with a prism.

But Chen Muwu couldn't find this kind of thing even if he dug three feet into the ground, because it would be more than ten years before the high-pressure mercury lamp was invented.

There are low-pressure mercury lamps, but their brightness is too dim, and most of the spectral lines are distributed in the ultraviolet invisible light region, so it is very difficult to operate the experiment.

As for the neon lamp, which is a common neon sign on the streets, the wavelength of the red light it emits is too long, and it is easy to mix the scattered spectrum with the fluorescence spectrum.

In this way, if you want to detect whether it is fluorescent or scattered light, you need to add an experiment to check the polarization of the light (because fluorescence is not polarized), which makes the experimental procedure even more cumbersome.

After thinking about it, Chen Muwu had no choice but to use the oldest method, separating a beam from sunlight for experiments, just like Newton, his old senior at Trinity College, used a prism to discover the dispersion of light.

In the darkroom that Rutherford had prepared for him, Chen Muwu cut a small hole in the curtain, drew a beam of sunlight from it, focused and diverged it with a lens group, and then made it pass through a blue-violet filter, uranium glass, and a collimating slit, so that he could barely use a near-monochromatic light source.

The reason why blue is chosen is because the wavelength of blue light is shorter, and the experimental phenomenon will be more obvious; The second is that the blue light is more distributed in the sunlight, which can also resist more refractive losses.

With the light source, and the experimental items pure water and pure ethanol, he still has a complete experimental principle in his brain, and with a little patience, this experiment is still very easy to do.

The only thing that limited the speed of Chen Muwu's experiments was that the sunlight could only be strongest in a few hours a day close to noon, and he could only do experiments within this period of time.

But even so, three days later, Chen Muwu successfully found the first scattering line of the water molecule in the eyepiece of the beamsplitter.

He adjusted his excitement and took the first photograph of the scattering lines on the photographic negative.

The next work is to transform the liquid in the container, such as ethanol, acetic acid, etc., and measure and record the specific data of the spectral lines in different liquids.

If Chen Muwu was a professor or group leader, then he could have handed over the subsequent experiments to his graduate students.

If Chen Muwu had done experiments on the most popular atomic nuclei or radioactivity in the Cavendish laboratory, and he had reported them to Rutherford after achieving the phased results, then it is estimated that Rutherford would soon send someone to assist him in his research.

It's a pity that Chen Muwu didn't meet either of the conditions, so he could only do it himself, changing the experimental materials again and again, and then recording the experimental data again and again.

Only Kapitsa occasionally came over with a pipe in his mouth to help during the lunch break, and by the way, told Chen Muwu what new progress had been made in his experiment with Blackett.
