Abstract
A semiempirical study is made of the deuteron-deuteron reaction cross section to determine its energy dependence at low energy and to permit more reliable extrapolation to energies below the experimental range. An energy-dependent correction to the simple WKB form is shown to be indicated by experimental data. The energy-independent normalization factor is then determined by comparison with the experimental data over the range of ten to one hundred kev bombarding energy. This provides a cross-section formula which is more suitable for extrapolation to the region around one kev.Keywords
