Abstract

The possibility of obtaining lifetime information from energy spectra of conversion electrons from a varying-potential (pulsed-bias) target is pointed out. The idea is based on the following fact: When a short beam-particle pulsed hits a target whose electric potential varies linearly with time, the mean energies of the conversion-electron groups produced are changed by amounts proportional to the nuclear lifetimes. The simultaneously occuring broadening of the electron line width depends mainly on the rate of change of the applied voltage and on the beam-pulse duration, and can thus be used e.g. in determining the latter quantity. Possible practical applications of the principle are discussed.
