Distillation of hydrogen isotopes for polarized HD target
hydrogen isotopes polarized HD target
2011/7/21
We have developed a cryogenic distillation system to purify Hydrogen-Deuteride (HD) gas for a polarized HD target in LEPS experiments at SPring-8. A small amount of ortho-H$_2$ ($\sim$0.01%) in the HD...

Proton-activation reactions on natural and enriched palladium samples were investigated via the activation technique in the energy range of E_p=2.75 MeV to 9 MeV, close to the upper end of the respect...
Anomalous pairing vibration in neutron-rich Sn isotopes beyond the N=82 magic number
Anomalous pairing vibration neutron-rich Sn isotopes magic number
2011/7/21
Two-neutron transfer associated with the pair correlation in superfluid neutron-rich nuclei is studied with focus on low-lying $0^+$ states in Sn isotopes beyond the N=82 magic number. We describe mic...
