Smith, D

A method of data collection for the determination of absolute disintegration rates by the 4$pi$$beta$$-$$gamma$ coincidence technique is described, which gives nearly an order of magnitude smaller variance, for a given total counting time, than conventional methods. It is applicable when the $beta$ counter output is proportional to the $beta$ particle energy. The principle, which is demonstrated for $sup 134$Cs, is to record the amplitudes of all the $beta$ pulses, followed by integration over variable limits. Expressions for dead time and resolving time corrections are derived. (orig.)
