摘要

The He-3 breakup reaction has been studied with 59.6 MeV vector-polarized deuterons at dp quasifree-scattering (QFS) conditions. In the coincidence energy spectra, large bumps corresponding to the QFS were observed. The calculation in the simple plane-wave impulse approximation (PWIA) qualitatively reproduces the energy spectra, but for the absolute cross sections, the ratio of the experimental values to the calculated values in the PWIA is about 0.27. As for the analyzing powers, the experimental values are greatly reduced as compared with the dp elastic-scattering data. The multiple-scattering effect has been investigated by a calculation taking account of the effects of double-scattering terms on the cross sections and the analyzing powers. [References: 22]
