Based on the experimental results of electron momentum spectroscopy of helium, the test of three wavehactions for the ground state of hellum has been performed.The conclusioll is that electron momentum spectroscopy is an useful tool for testing electron wavefunctions of atoms and molecules.
In this letter, the development of an electron momentum spectrometer, which is the first in China, has been described shortly, and using this spectrometer, the experimental results on the electron momentum spectroscopy of helium were reported.
