Abstract
The beam tubeP2 of the 4 MW FRM pool reactor was used as the neutron source for this nuclear spectroscopy study. An 8.5 and 13.5 cm lithium drifted germanium detector were used as gamma ray detector to measure the low energy prompt photon emissions from thermal neutron capture in 18 elements (12 rare earth elements) having aσ/A value greater than 0.1. The energy region was from 50–500 keV. Energy and intensity of the gamma ray lines are given.
