Vector analyzing power of pi Li+7 scattering in the region of the Delta(33) resonance

摘要

Within Glauber diffraction theory, the vector analyzing power iT(11) is calculated at three energies of positively charged pions, 134, 164, and 194 MeV, incident to Li-7 nuclei. These energy values lie in the region of the Delta(33) resonance in pi N+/- interaction, the resonance maximum being at 180 MeV The calculation of iT(11) was performed with several model Li-7 wave functions, including the at-cluster and shell-model ones. The properties of pi Li+7 scattering are found to be sensitive to the structural features of the target nucleus. A comparison of the results of the calculations with experimental data shows that the wave functions in question and the potentials used to calculate them are quite appropriate.
