✦ Synopsis

Efficiency

functions were measured by using a bi-dimensional dataacquisition system and a magnetic tape sub system.

In the measurement, the data of pulse height and time relation of S and y signals were recorded on a magnetic tape. After measurement, all data stored on the tape were analysed and the efficiency functions were obtained by the "computer-discrimination method". This method was applicable for the sources with disintegration rates lower than 15 kBq and the smooth efficiency functions were obtained for the nuclides of "Fe and 134Cs in short time.
