N. Nose et al., CLUSTER-MODEL CALCULATION OF QUADRUPOLE EFFECTS IN PION-SCATTERING FROM LI-7, Physical review. C. Nuclear physics, 50(1), 1994, pp. 321-328
We have studied the quadrupole effects in pion elastic and inelastic s
cattering from Li-7. A single channel alpha-t cluster model is used to
calculate the wave function for the ground and the first excited stat
es of Li-7. The quadrupole effects are shown to be appreciably large i
n pion-Li-7 elastic scattering. We also calculated the second-rank ten
sor polarization and compared it with the recent experimental data.
