In order to investigate the possible influence of metallic environment on the alpha decay process, we have measured the Sm activities in the hosts of metal samarium and SmO . The Sm half-life was found to be (1.06±0.01)×10 y in metal samarium and (1.07±0.01)×10 y in SmO , respectively. No significant change has been observed within the experimental uncertainty. The absolute half-life presented here is consistent with the recommended value. [ABSTRACT FROM AUTHOR]

The angular distribution of the 2H ( 6He,7Li n reaction was measured with a secondary 6He beam of 36.4MeV for the first time. The proton spectroscopic factor of 7Li ground state was extracted to be 0.42±0.06 by normalizing the calculational differential cross-sections with the distorted-wave Born approximation to the experimental data. It was discussed that the uncertainty of extracted spectroscopic factors from the one-nucleon transfer reactions induced by deuteron might be reduced by determining the volume integrals of imaginary optical potentials precisely.
