Abstract
Abstract The 7 Li( p , γ 0 ) 8 Be reaction is studied in a microscopic cluster model. All relevant subsystem properties are well reproduced. The calculated astrophysical S -factor is in good agreement with the experimental data, although some M1 strength is missing in the 1 + ; 1 resonance region, and there is no contribution from the 1 + ; 0 state. Our model predicts, in contradiction to experiment, a dominant I = 1 channel spin contribution to the cross section. We estimate an M1 strength of 3.5% at 80 keV. By assuming the experimental resonance parameters and channel spin ratio for the first 1 + state that M1 strength is 6.3%, in good agreement with an R -matrix analysis.
