Abstract
The radiative capture of light particles (≤ alphas) is a well-established mechanism that has been used for a variety of studies such as the spectroscopy of shell-model states, the decay of giant resonances, and the properties of isobaric analog resonances. In contrast, comparatively little is known about the radiative capture of heavy ions. This is mainly due to the small cross sections encountered. The Coulomb barriers that must be overcome for heavy-ion fusion are much higher. This, together with consistently larger Q values, leads to much higher excitations in the compound nuclei. States at such high energies tend to have much larger total widths, with the result that the branching ratios for radiative decay Γγ/Γ tend to be much smaller than in light-ion capture. Consequently, only a few experiments relating to this area of heavy-ion science have been performed. These have been compiled and are listed in Table 1.
