The photoelectric effect is one of the most fundamental light-matter interactions, which is widely used in probing ultrafast dynamics in atoms, molecules and condensed matters. It has been in the ...
Using a home-built time-of-flight mass spectrometer (TOFMS), a research team led by Prof. Haiyang Li from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has ...
Laser physicists in Munich have measured a photoionization -- in which an electron exits a helium atom after excitation by light -- for the first time with zeptosecond precision. A zeptosecond is a ...
