Development and application of a He Neutron Spin Filter at J-PARC
T. Okudaira, T. Oku, T. Ino +22
We are developing a neutron polarizer with polarized He gas, referred to as a He spin filter, based on the Spin Exchange Optical Pumping (SEOP) for polarized neutron scatte…
Transverse asymmetry of rays from neutron-induced compound states of
T. Yamamoto, T. Okudaira, S. Endo +17
A correlation term in the reaction has been studied utilizing epithermal polarized neutrons and germanium det…
Measurement of the total neutron scattering cross section ratios of noble gases of natural isotopic composition using a pulsed neutron beam
Christopher C. Haddock, Masayuki Hiromoto, Katsuya Hirota +8
Precision measurements of slow neutron cross sections with atoms have several scientific applications. In particular the n-He s-wave scattering length is important to know bo…
Improved determination of thermal cross section of 14N(n,p)14C for the neutron lifetime measurement
R. Kitahara, K. Hirota, S. Ieki +21
In a neutron lifetime measurement at the Japan Proton Accelerator Complex, the neutron lifetime is calculated by the neutron decay rate and the incident neutron flux. The flux is o…
Precise neutron lifetime experiment using pulsed neutron beams at J-PARC
Naoki Nagakura, Katsuya Hirota, Sei Ieki +22
The neutron lifetime is one of the basic parameters in the weak interaction, and is used for predicting the light element abundance in the early universe. Our group developed a new…
