Abstract

We report about our recently upgraded PGAA-NIPS facilities, which use a guided cold neutron beam produced by the 10 MW Budapest Research Reactor. The two facilities provide excellent means for determining partial gamma ray cross sections for products produced in the sample by neutron capture reactions. Both stations are equipped with HPGe detectors to detect the gamma rays coming from the excited nuclei of the samples. We present our methodology developed for the determination of thermal capture cross section of various target isotopes including the radioactive 99Tc, 129I nuclei and of the partial gamma ray cross sections of 235U and 238U nuclei. The chopped beam option provides a good opportunity to study short-lived products. An overview of our recent capture cross section experiments is also given.
