3He(d, p)4He Reaction at Intermediate Energies

We have measured the cross sections and the polarization observables for the ³He(d,p)⁴He reaction at E_d =140, 200, and 270 MeV. This work aims to investigate the high momentum component of deuteron D-state wave function and the mechanism for the one-nucleon transfer reaction at intermediate energies. The measurement was carried out by using the spectrograph SMART at RIKEN Accelerator Research Facility. A cryogenic ³He gas target with a density of 6.6 ×10²⁰ cm^-3 was bombarded by a polarized deuteron beam. The data are compared with the calculation based on the one-nucleon exchange approximation and data from the d + p backward scattering.
