First measurement of the 2H(6He,7Li)n angular distribution and proton spectroscopic factor in 7Li.

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.
