This paper introduces a new approach to measure the muon magnetic moment anomaly |$a_{\mu} = (g-2)/2$| and electric dipole (EDM) |$d_{\mu}$| at J-PARC facility. The goal of our experiment is |$a_{\mu}$| using an independent method with factor 10 lower momentum, 20 smaller diameter storage-ring solenoid compared previous ongoing |$g-2$| experiments unprecedented quality storage field. Additional significant differences from present experimental include 1000 transverse emittance beam...
We performed in-gas-cell laser ionization spectroscopy of $^{194,196}\mathrm{Os}$, which were produced by multinucleon transfer reactions at the KEK Isotope Separation System (KISS). The nuclei interest identified through $\ensuremath{\beta}$-decay and a newly applied multireflection time-of-flight mass spectrograph (MRTOF-MS). From study resonance spectra, isotope shifts (ISs) transition ${\ensuremath{\lambda}}_{1}=247.758$ nm for $^{194}\mathrm{Os}$ $^{196}\mathrm{Os}$ measured first time....
We have developed the KEK Isotope Separation System (KISS) at RIKEN to study nuclear structure of nuclei in vicinity neutron magic number $$N=$$ 126 from astrophysical perspective. These neutron-rich been produced by using multinucleon transfer (MNT) reactions with combinations low-energy $$^{136}$$ Xe beam and production targets W, Ir, Pt. At KISS facility, radioisotopes are ionized applying in-gas-cell laser ionization technique. In this process, we can perform spectroscopy refractory...
Muons have been accelerated by using a radio-frequency accelerator for the first time. Negative muonium atoms (${\mathrm{Mu}}^{\ensuremath{-}}$), which are bound states of positive muons (${\ensuremath{\mu}}^{+}$) and two electrons, generated from ${\ensuremath{\mu}}^{+}$'s through electron capture process in an aluminum degrader. The ${\mathrm{Mu}}^{\ensuremath{-}}$'s initially electrostatically injected into quadrupole linac (RFQ). In RFQ, to 89 keV. identified momentum measurement time...

We have measured the muon beam profile after acceleration using a radio frequency quadrupole linac (RFQ). Positive muons are injected to an aluminum degrader and negative muoniums (Mu−) generated. The generated Mu−'s extracted by electrostatic lens accelerated 89 keV RFQ. transported monitor (BPM) through magnet pair bending magnet. BPM consists of micro-channel plate, phosphor screen, CCD camera. in vertical direction is consistent with simulation. This measurement one milestones for...
Prompt k0-factors are determined for the strong non-1/v absorbers such as cadmium and gadolinium, relative to chlorine by using new SNU-KAERI PGAA (Prompt Gamma Activation Analysis) facility at Korea Atomic Energy Research Institute. For experimental k0 determination, modified Høgdall formalism including correction factor influence of neutron spectrum capture cross section on reaction rate is used. The sensitivity data measured Gd + NaCl solutions Cd with various elemental contents....
