Potential model analysis of low energy /sup 2/H(d,. gamma. )/sup 4/He fusion data
Previously experimental data on the /sup 2/H(d,..gamma..) /sup 4/He reaction have been analyzed within a potential model of structureless particles to derive quantitative information about the /sup 4/He ground state. We have tested the applicability of the potential model by comparing cross sections calculated for a wide range of Woods-Saxon parametrizations covering those of previous studies with recent low energy /sup 2/H(d,..gamma..) /sup 4/He fusion data. We find that the results for the capture cross sections from the d+d S-wave into the D-state component of the /sup 4/He ground state, which dominate the fusion data at Eless than or equal to200 keV, are very sensitive to the parametrization of the nucleus-nucleus potential. Hence simple potential model studies seem not to be an appropriate tool for quantitative analysis of low energy /sup 2/H(d, ..gamma..) /sup 4/He fusion data.
