Erratum: Systematics of cluster decay modes [Phys. Rev. C65, 054308 (2002)]

Abstract

In Fig. 1 the 24,25 Mg cluster decay modes of 235 U (Zϭ92,Nϭ143) should be replaced by 24,25 Ne. The corrected Fig. 1 is given below. The conclusions are not affected.FIG. 1. Nuclear chart of experimentally determined cluster decay modes. The type of cluster decay, and the decimal logarithm of the half-life in seconds for cluster and ␣ decay, is given for each parent nucleus with a specified proton and neutron number.PHYSICAL REVIEW C 66, 049902͑E͒ ͑2002͒

Relativistic mean field description of cluster radioactivity

“…Therefore, the conclusions and inferences drawn here will generally remain valid. We now present and discuss the calculated ground-state properties for the parent nuclei involved in the observed cluster decays [7]: 221 The calculated binding energies reproduce the experiment [25] well, as expected. The maximum departure from the experiment is about 5 MeV, which amounts to ∼0.25%.…”

“…The corresponding experimental values [7] are also shown. Generally, the error bars quoted with the half-lives are smaller than an order of magnitude (see, for example, [6,33,34] The experimental half-lives have been adopted from [7]. the error bars on the experimental half-lives are not shown explicitly in the figure.…”

“…A number of experimental investigations since then have been reported (e.g., [3][4][5][6]), confirming the first experiment and adding some heavier decay modes. So far, about 30 such decays have been reported [7], and the search for other possible cluster decays is ongoing. However, such measurements are difficult to make because of the very small branching ratio of the cluster decay mode to the α decay mode of the parent nuclei [6,7].…”

However, such measurements are difficult to make because of the very small branching ratio of the cluster decay mode to the α decay mode of the parent nuclei [6,7].On the theoretical front, primarily two kinds of models have been advanced to describe the cluster decay modes: 1) the unified models, which treat the alpha decay, heavy cluster decay, and cold fission on similar footings, and 2) the cluster models. The analytic super asymmetric fission model (ASAFM) [8] and the effective liquid drop model (ELDM) [9] are examples of the former, whereas the 'square well' approach of Price et al…”
