Improved measurements of neutron lifetime with cold neutron beam at J-PARC
Y. Fuwa, T. Hasegawa, K. Hirota +28
The ``neutron lifetime puzzle'' arises from the discrepancy between neutron lifetime measurements obtained using the beam method, which measures decay products, and the bottle meth…
Measurement of rays from LiF tile as an inner wall of a neutron-decay detector
J. Koga, S. Ieki, A. Kimura +12
A neutron lifetime measurement conducted at the Japan Proton Accelerator Research Complex (J-PARC) is counting the number of electrons from neutron decays with a time projection ch…
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…
Fundamental physics activities with pulsed neutron at J-PARC(BL05)
Kenji Mishima, Shogo Awano, Yasuhiro Fuwa +37
"Neutron Optics and Physics (NOP/ BL05)" at MLF in J-PARC is a beamline for studies of fundamental physics. The beamline is divided into three branches so that different experiment…
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…
Development of time projection chamber for precise neutron lifetime measurement using pulsed cold neutron beams
Y. Arimoto, N. Higashi, Y. Igarashi +24
A new time projection chamber (TPC) was developed for neutron lifetime measurement using a pulsed cold neutron spallation source at the Japan Proton Accelerator Research Complex (J…
