✦ Synopsis

A new method is described for determining neutral atomic and molecular lifetimes by measuring delayed coincidences between inelastically scattered electrons and the subsequent decay photons. The lifetime of the 4% state of helium. as measured b-v this method, is 73 i 2 nsec.

We have developed a new method for lifetime measurements of excited copper halides formed in reactive collision of metastable \*D copper atoms with a halogen compound. The method is based on observation of the temporal decay of the population of the excited molecular levels, which follows a fast dep
