Absolute He polarimetry for a double-chambered cell using transmission of thermal neutrons
A. Watanabe, K. Sekiguchi, T. Ino +5
We present an absolute He polarimetry method based on thermal neutron transmission for a double-chambered cell. This method utilizes the fact that a He nucleus has a large…
Proton- elastic scattering at intermediate energies
A. Watanabe, S. Nakai, Y. Wada +42
We present a precise measurement of the cross section, proton and analyzing powers, and spin correlation coefficient for - elastic scattering near…
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…
