Title: Reactions in the {sup 8}B and {sup 8}Li compound systems

Abstract

Calculations are reported for reactions in the {sup 8}B and {sup 8}Li compound systems with the recoil corrected continuum shell model. Comparison with observed structure indicates that the spin-orbit component of the M3Y interaction must be modified near the middle of the p shell. Calculations are performed with three spin-orbit strengths. The prediction for {sup 7}Be(p,{gamma}){sup 8}B, based on this model and available data, is that S{sub 17}(0) equals 21.63 eV b and S{sub 17}(20) 21.02 eV b. Calculations for {sup 7}Li(n,{gamma}){sup 8}Li indicate that the {sup 8}Li, 1{sub 2}{sup +} state is nearly degenerate with the 3{sup +} state. It is shown that a measurement of {sup 7}Li(n,{gamma}){sup 8}Li(1{sub 1}{sup +}) can locate the 0{sup +} state. It is also shown that {sup 7}Be(p,p{sup '}){sup 7}Be(1/2{sup -}) can locate the 1{sup +} and 0{sup +} strength in {sup 8}B.
