Inclusive reaction 93Nb(p,α) at an incident energy of 160 MeV.

The inclusive 93Nb(p,α) reaction to the continuum was investigated at an incident energy of 160 MeV. Emission-energy angular distributions for cross sections as well as analyzing powers were explored. A range of scattering angles from 15° to 60° (lab.) was covered and α-particle emission energies from ≈30 MeV to the kinematic limit were measured. As in our earlier work, the experimental distributions were compared with a multistep direct theory combined with a knockout reaction mechanism as the terminating step in the a-particle emission. Reasonable agreement between the theoretical predictions and the experimental double-differential cross section and analyzing-power angular distributions were obtained. [ABSTRACT FROM AUTHOR]
