Spin effects in π+‐6Li↘ and π+‐7Li↘ scattering

Vector and tensor analyzing powers were measured for π+‐6Li↘ and π+‐7Li↘scattering in the angular range between 50° and 110° at several pion energies in the region of the Δ(3,3) resonance. The data are compared to predictions from a coupled channel model. Within this model the sensitivity to variations of the nuclear structure input and the reaction mechanism are investigated.

Measurement of the vector analyzing power iT sub 11 in. pi. sup + - sup 6 L rvec i scattering

The vector analyzing power {ital iT}{sub 11} was measured for {pi}{sup +}-{sup 6}{rvec L}i elastic and inelastic scattering (3{sup +}, 2.19 MeV) at 100, 134, 164, and 219 MeV, in an angular range between 40{degree} and 125{degree} using a vector polarized {sup 6}LiD target. Sizable spin effects were observed over most of the angular range. The data were compared with a number of theoretical predictions based on different scattering models and nuclear structure input. None of the calculations is able to reproduce the data set; however, it appears that the vector analyzing power {ital iT}{sub 11} is mostly sensitive to the nuclear wave function chosen. The angular distribution of {ital iT}{sub 11} in {pi}{sup +}-{sup 6}Li elastic and inelastic scattering is discussed in terms of nuclear form factors and elementary {pi}{ital N} amplitudes.
