Short-Range Tests of the Gravitational Inverse-Square Law
Jiro Murata, Takuhiro Fujiie, Sae Suzuki
Experimental constraints on the gravitational inverse-square law at short range are presented, employing a consistent formalism across a wide range of length scales. We provide com…
Proof-of-Principle Experiment on a Displacement-Noise-Free Neutron Interferometer for Gravitational Wave Detection
Shoki Iwaguchi, Takuhiro Fujiie, Taro Nambu +13
The displacement-noise-free interferometer (DFI) is designed to eliminate all displacement-induced noise while retaining sensitivity to gravitational wave (GW) signals. Ground-base…
Lifetime measurement of the muonic atoms of enriched Si isotopes
R. Mizuno, M. Niikura, S. Akamatsu +12
Background: A muonic atom, composed of a negative muon and an atomic nucleus, undergoes two primary decay processes: muon-electron decay and muon nuclear capture. The branching rat…
Current-readout technique for ultra-high-rate experiments
Maki Wakata, Shoei Akamatsu, Takuhiro Fujiie +9
This study developed a new current-readout technique capable of handling measurements with high count rates reaching 1 Gcps. By directly capturing the output current of a photomult…
Demonstration of Near-Epithermal Neutron Reflective Optics
Takuhiro Fujiie, Ryota Abe, Masahiro Hino +11
Specular reflection of neutrons on material surfaces has been demonstrated in the energy range of 0.09-0.7 eV. The results suggest that the applicable energy range of reflective ne…
Development of Neutron Interferometer using Multilayer Mirrors and Measurements of Neutron-Nuclear Scattering Length with Pulsed Neutron Source
Takuhiro Fujiie, Masahiro Hino, Takuya Hosobata +6
This study entailed the successful deployment of a novel neutron interferometer that utilizes multilayer mirrors. The apparatus facilitates a precise evaluation of the wavelength d…
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…
