Abstract

The total photoabsorption cross sections of the six-body nuclei are calculated including a complete final state interaction via the Lorentz integral transform method. The effect of nucleon-nucleon central P-wave forces is investigated. Comparing to results with central potentials containing S-wave forces only, one finds considerable more strength in the low-energy cross sections and a rather strong improvement in comparison with experimental data, in particular for ⁶Li.
