摘要：

The inelastic scattering of 162-MeV π+ and π- by Si28 was studied at larger momentum transfer. Several high-spin particle-hole states are observed to be preferentially excited in this reaction. These include the 9.70-MeV (5-,T=0), 11.58-MeV (6-,T=0) and 14.36-MeV (6-,T=1) states. The ratios of the cross sections of the 6-, T=0 state to the 6-, T=1 state are 1.5-0.2+0.4 for π+ and 1.7±0.4 for π-, in contrast to ratios of about 4 predicted by simple distorted-wave impulse-approximation calculations. © 1979 The American Physical Society.
