Stellar neutron capture cross section of Tc-99

摘要

The neutron capture cross section of Tc-99 has been measured from 3 eV to 90 keV at the pulsed white neutron source GELINA at Geel using the time-of-flight method. The Tc-99(n,gamma) reaction was detected at a flight path of 28.32 m with two C6D6 total energy gamma-ray detectors using a pulse height weighting method. From these data the Maxwellian-averaged neutron capture cross section has been calculated at several temperatures between 5 and 100 keV. [References: 10]
