Spin decomposition of the {bold {Delta}} resonance cross section using the {sup {bold 12}}{ital C}({ital p{searrow},}n{searrow}) reaction at {ital E{sub p}}=795 MeV
1996
The first ({ital p},{ital n}) polarization-transfer measurements for delta production on a nuclear target are presented for the {sup 12}C({ital p}{searrow},{ital n}{searrow}) reaction at 0{degree} and 795 MeV. Polarization observables are used to extract the spin-longitudinal, spin-transverse, and spin-independent partial cross sections. In the spin-longitudinal channel, fair agreement is found between experiment and a model which includes a strongly attractive residual interaction. A large unexpected enhancement in the spin-transverse cross section is observed. {copyright} {ital 1996 The American Physical Society.}
