FACILITY (NGEN,3CPRNPC) PD-300 neutron generator 3271400100010
SAMPLE About 8 g of Er2O3 powder of natural isotopic 3271400100011
composition (99.99% pure) was pressed at 10 ton/cm2, 3271400100012
and a pellet, 0.5 cm thick and 2.0 cm in diameter was 3271400100013
obtained. 3271400100014
DETECTOR (HPGE) The crystal geometry is 70.1 x 72.3 mm in 3271400100015
diameter and length. The relative efficiency is about 3271400100016
68%, and energy resolution is 1.69 keV at 1332 keV 3271400100017
gamma ray from Co-60. 3271400100018
(FISCH) The neutron flux was monitored by a uranium 3271400100019
fission chamber. 3271400100020
METHOD (ACTIV) Irradiation of the samples was lasted 152 min 3271400100021
with a yield around 3E10 to 4E10 n/s, and cooled for 3271400100022
6-83 min. 3271400100023
