New type of decay of heavy nuclei intermediate between fission and. cap alpha. decay
A new type of decay intermediate between fission and ..cap alpha.. decay is predicted in heavy and superheavy nuclei. Two limiting approaches are presented in which this decay is treated as fission with maximal asymmetry of the fragment masses or as emission of a heavy cluster. It is shown that, if strongly mass-asymmetric two-body fragmentation is treated as emission of a heavy cluster, agreement is achieved with the predictions made earlier of a strongly asymmetric type of fission representing a new decay mode intermediate between ..cap alpha.. decay and fission. It is also shown that ..cap alpha.. decay can be successfully regarded as a fission process with different charge densities of the two fragments and a precisely determined mass ratio.
