Description

The 21+, 41+, and 02+ states in /sup 28/Si have been observed with π+ scattering at 50 MeV. These data, along with existing data for /sup 28/Si are compared to coupled channel calculations. This analysis produces a larger β2 than previously found in low energy distorted wave calculations and is consistent with results from resonance energy studies. The interference of the one- and two-step contributions make the calculated 4+ cross section quite sensitive to the sign of β4. The sensitivity to the πA optical model is discussed
