Pendellösung Interferometry Probes the Neutron Charge Radius, Lattice Dynamics, and Fifth Forces
Benjamin Heacock, Takuhiro Fujiie, Robert W. Haun +11
Structure factors describe how incident radiation is scattered from materials such as silicon and germanium and characterize the physical interaction between the material and scatt…
Energy dependent angular distribution of individual -rays in the La(, )La* reaction
T. Okudaira, S. Endo, H. Fujioka +14
Neutron energy-dependent angular distributions were observed for individual -rays from the 0.74 eV p-wave resonance of La+ to several lower excited states of …
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…
Observation of Pendellösung Fringes by Using Pulsed Neutrons
Shigeyasu Itoh, Masaya Nakaji, Yuya Uchida +2
Pendellösung interference fringes of a single silicon crystal were observed by using pulsed cold neutrons. The nuclear scattering length of silicon was obtained as (4.159\pm0.003(s…

Coherent double neutral-pion photoproduction on the deuteron, {}, has been experimentally studied at incident photon energies ranging from 0.75 to 1.15 GeV. T…
A Search for Possible Long Range Spin Dependent Interactions of the Neutron From Exotic Vector Boson Exchange
Christopher C. Haddock, Joseph Amadio, Eamon Anderson +26
We present a search for possible spin dependent interactions of the neutron with matter through exchange of spin 1 bosons with axial vector couplings as envisioned in possible exte…
Differential cross section and photon beam asymmetry for the gamma p -> pi+ n reaction at forward pi+ angles at Egamma=1.5-2.95 GeV
H. Kohri, S. Y. Wang, S. H. Shiu +46
Differential cross sections and photon beam asymmetries for the gamma p -> pi+ n reaction have been measured for 0.6<cos(theta)<1 and Egamma=1.5-2.95 GeV at SPring-8/LEPS. The cros…
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…
A study of event mixing for two-pion Bose-Einstein correlations in the γp -> π^0 π^0 p reaction
Q. He, J. Ai, T. Ishikawa +10
We develop an event mixing technique with a missing mass consistency (MMC) cut and a pion energy (PE) cut for the measurement of two-pion Bose-Einstein correlations (BEC) in reacti…
Photoproduction of neutral kaons on the liquid deuterium target in the threshold region
K. Tsukada, T. Takahashi, T. Watanabe +32
The photoproduction process of neutral kaons on a liquid deuterium target is investigated near the threshold region, Egamma = 0.8-1.1 GeV. K0 events are reconstructed from positive…
