Entering the field of zeptosecond measurement

11-Nov-2016

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. This is the greatest accuracy of time determination ever achieved, as well as the first absolute determination of the ...
