Polarization transfer in inelastic proton scattering from 4{sup {minus}} states in {sup 16}O at 350 MeV
- Simon Fraser University, Burnaby, British Columbia, V5A 1S6 (CANADA)
This experiment has measured cross sections, analyzing powers, and the spin observables {ital P}, {ital D}{sub {ital ss}}{sup {prime}}, {ital D}{sub {ital sl}}{sup {prime}}, {ital D}{sub {ital nn}}{sup {prime}}, {ital D}{sub {ital ll}}{sup {prime}}, {ital D}{sub {ital ls}}{sup {prime}} for the reaction {sup 16}O({ital p},{ital p}{sup {prime}}) at 350 MeV populating three 4{sup {minus}} states. These {open_quote}{open_quote}stretched{close_quote}{close_quote} states, at excitation energies of 17.79 MeV, 19.80 MeV (both mainly {ital T}=0), and 18.98 MeV (mainly {ital T}=1), have well known nuclear structure and are used as a nuclear filter to examine the tensor and spin-orbit components of the effective nucleon-nucleus interaction at 350 MeV. A complete set of spin observables was obtained at an angle of 22{degree} in the laboratory frame, whereas the {ital D}{sub {ital ss}}{sup {prime}} and {ital D}{sub {ital sl}}{sup {prime}} observables were measured at laboratory angles of 17, 22, 27, and 32 degrees. The data are compared with distorted-wave impulse approximation calculations from several theoretical models. {copyright} {ital 1996 The American Physical Society.}
