Evidence for a quasi-bound state in the reaction

R. Kobayakawa, J. K. Ahn, S. Ajimura +34

The reaction has been studied to search for a quasi-bound state using the LEPS2 solenoid spectrometer at SPring-8. A localized enhancement concentrated…

SPring-8 LEPS2 beamline: A facility to produce a multi-GeV photon beam via laser Compton scattering

N. Muramatsu, M. Yosoi, T. Yorita +48

We have constructed a new laser-Compton-scattering facility, called the LEPS2 beamline, at the 8-GeV electron storage ring, SPring-8. This facility provides a linearly polarized ph…

Monitoring the build-up of hydrogen polarization for polarized Hydrogen-Deuteride (HD) targets with NMR at 17 Tesla

T. Ohta, M. Fujiwara, T. Hotta +5

We report on the frozen-spin polarized hydrogen--deuteride (HD) targets for photoproduction experiments at SPring-8/LEPS. Pure HD gas with a small amount of ortho-H2 (~0.1%) was li…
