Spin observables for the 208Pb(p,n)208Bi reaction at 135 MeV
Abstract
We measured the spin observables Ay, P, and SNN' for the 208Pb(p,n)208Bi reaction at 135 MeV at laboratory angles of 0°, 3°, 6°, and 9°. The overall energy resolution was about 1 MeV. Data for SNN' are compared with distorted-wave impulse-approximation calculations that use random-phase approximation wave functions. Comparisons are also made for the 48Ca(p,n)48Sc reaction. The agreement between these calculations and the data is generally good, after adjustment of the nucleon-nucleon interaction in the random-phase approximation calculations to place the 0+ isobaric-analog states at the correct excitation energies. A single adjustment of the nucleon-nucleon force works for both target nuclei.
