| Summary: | -3% -2%) of the E2 energy-weighted sum rule (EWSR) for (deformed potential) model. 1--2 state was fit well using the electromagnetic B(E2) 1=2 calculations corresponding to 45+5% (42+5% agreement with previous deformed potential results. The agreement with previous work. The experimental Ex=17.42 MeV and 1=3 states were nearly the same for both cases. angles. The experimental Ex=13.2 MeV and Ex=15.6 MeV peaks angular range, even though cross sections for low-lying 1=2 B(EI) values. The experimental Ex=16.08 MeV peak was fit by calculations.116 For n. the data for the Ex=1.29 MeV changed significantly when hybrid folding model potential considerably smaller than from previous folding model corresponding to 19:t2% (4O-t2%) of the EO EWSR and 73︢% (8+5% -3% ) of the E2 EWSR with the folding EX=2.27 MeV 1=3 state was not well reproduced at smaller EX=21.8 MeV peak was fit by an 1=3 calculation corresponding GMR has been located, cross sections for p GMR excitation of the E2 EWSR and 1061︢4% of the EO EWSR, in excellent peak was fit by a combination of 1=0 and 1=2 calculations Potential parameters were obtained from recent elastic potential results.
