Abstract

In bombardments of 90Zr, 92Zr and 94Mo with 90Zr ions at energies near the Coulomb barrier, radiative fusion has been observed where the compound nuclei do not evaporate nucleons but emit only γ radiation. The deexcitation by the emission of γ radiation only is probably favoured by the very low excitation energy of the compound nuclei. In addition a substantial enhancement of the El γ strength in the deexcitation process seems to be necessary to reproduce the experimental cross sections. To obtain further information on the fusion process, the spectral distributions of the deexcitation γ transitions as well as their multiplicities have been measured in the reactions 90Zr, 96Zr + 90Zr.
