Measurements of neutron capture cross sections using a 4$\pi $Ge spectrometer at the J-PARC/MLF/NNRI
ORAL
Abstract
The measurements of neutron capture cross sections have been started using a 4$\pi $Ge spectrometer at the neutron nucleus reaction instrument (NNRI) in the J-PARC/MLF. First test measurements using the spectrometer have been performed for radioactive samples such as Cm-244, etc. The test experiments have demonstrated the capability of measuring the neutron capture cross section of Cm-244 with a sample mass of less than 1mg. We will report preliminary results of the initial experiments, and discuss the new capability.
*Present study is the result of ``Study on nuclear data by using a high intensity pulsed neutron source for advanced nuclear system'' entrusted to Hokkaido University by the Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT).
