Researchers Began To Use Laser Pointers To Detect Anti-atoms
After isolating the anti-atoms, researchers began to use lasers to detect anti-atoms. When the laser pointer hits an atom. If the wavelength of the light is right, the energy of the light will be absorbed by the electrons of the atoms. Using this extra energy, electrons can jump to a higher energy level orbit. After that, the electrons will release energy in the form of light and return to their original orbit. During the research, the antimatter was frozen to 0.5 Kelvin. Such cooling is necessary to prevent a single anti-atom from moving too fast and escaping from the "trap". Researchers hope to perform spectral analysis on the light emitted by electrons. Different elements will release laser pointers of different wavelengths, but any two hydrogen atoms should produce light of the same wavelength. Moreover, according to known physics. Anti-hydrogen atoms should also produce the same spectrum.

Researchers conducted 3 sets of 11 trials. Different laser pointers are set in the first two groups, and the third group is used as a control without laser. Such experimental settings can rule out some system problems that suddenly appear or may affect the results. These experiments can also help identify cosmic rays in the background. When cosmic rays collide with particles above the atmosphere, they will produce secondary particles that can enter the experimental equipment, and these particles may be mistaken for light emitted by isolated antihydrogen atoms. The experiment is exciting, but the result is not exciting. So far, the spectra from anti-hydrogen atoms are in complete agreement with that of hydrogen atoms, confirming part of the basic theory of the Standard Model. If there are different laser pointer spectra in the experiment. Then the physics community may have to make waves.
