Abstract

A "4π germanium spectrometer" was developed for measurements of neutron capture cross sections of minor actinides and long-lived fission products. It was installed on the Beam Line No. 04 of the Materials and Life Science Experimental Facility of the Japan Proton Accelerator Research Complex. The time-of-flight method is used to measure the cross sections. To obtain characteristics of the spectrometer, a measurement was done of prompt gamma rays emitted following neutron capture reactions of gold whose cross section was well studied. In the present paper, we show the procedure of analysis of the data obtained with the spectrometer and discuss the characteristics to measure neutron capture cross section.
