SAMPLE 1-microgram of Pu-241 for primary sample. Fission 1089400100013
chamber uses PuO(2), 99-percent Pu-241 1089400100014
DETECTOR (GELI) 90-cubic cm high resolution GeLi detector. 1089400100015
(FISCH) Pu-241 loaded fission chamber 1089400100016
METHOD GeLi detector calibrated using fission product gamma 1089400100017
rays from irradiated Pu in fission chamber. Detector 1089400100018
efficiency calibrated at 200-mm and other distances 1089400100019
using gammas from varied sources. 1089400100020
CORRECTION Gamma-ray spectra data corrected for- 1089400100021
-irradiation time 1089400100022
-waiting time 1089400100023
-counting time intervals 1089400100024
Data from fission chamber corrected for- 1089400100025
-loss of fragments in foil 1089400100026
-low pulse height events (0.8+-0.2 percent) 1089400100027
-dead time (less than 0.2-percent) 1089400100028
