✦ Synopsis
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 depopulation of Cu*(*D) levels in the reaction zone. This allows the lifetimes of all molecular states formed in the reactive collision, including very high vibrational levels, to be determined. We have measured lifetimes of several excited states in CuF, CuCl and CuBr, in the range of l-l 5 ps.
