Reaction mechanism for natural parity (p,p') transitions in B10
PHYSICAL REVIEW C(2005)
摘要
We report angular distribution measurements of the cross section, analyzing power, induced polarization, and all polarization transfer coefficients for the natural parity transitions in B-10((p) over right arrow, (p) over right arrow)B-10 at 197 MeV. All of the transitions closely follow the pattern for spin-1/2 scattering from spin-0, namely A = P, D-SS' = D-LL', and D-SL' = -D-LS'. Small deviations from D-NN' = 1 reflect spin-flip contributions to these transitions. Distorted wave impulse approximation calculations were generally successful, supporting the use of an empirical effective nucleon-nucleon interaction, the inclusion of channel-coupling in the ground state and the 3(+) <-> 4(+) transition, and the procedure of increasing the L = 2 strength of shell-model particle-hole matrix elements to match the collective contribution to these transitions.
