Research Abstract |
At RCNP, we study^<16> O(p, d)^<15> O reaction at E_p=200~ 400 MeV. The cross section of transitions to the discrete excited states in^<15> O have been measured. The abnormal enhancement of the cross section has been observed in the transition to the positive parity states at high energy. This anomaly is understood quantitatively as an effect of high-momentum nucleon produced by the tensor force and thus suggests a direct evidence of the tensor force in a nucleus. At GSI, measurements of proton elastic scattering have been made to study the density distribution of neutron rich Ni isotopes. We could have extended the measurement up to^<70> Ni. The data are under analysis. We will obtain density distribution of medium mass neutron-rich nuclei for the first time.
