摘要：
We calculated rates of beta(-) decay to both continuum and bound states separately for some fully ionized (bare) atoms in the mass range A approximate to 60-240. One of the motivations of this work is that the previous theoretical calculations were very old and/or informatically incomplete. Probably no theoretical study on this subject has been done in the last three decades. For the calculation, we have derived a framework from the usual beta(-) decay theory used by previous authors. Dependence of the calculated rates on the nuclear radius and neutral atom Q values have been examined. We have used the latest experimental data for nuclear and atomic observables, such as beta(-) decay Q values, ionization energy, neutral atom beta(-) decay branchings, and neutral atom half-lives. Results of beta(-) decay rates for decay to continuum and bound states and the enhancement factor due to the bound state decay for a number of nuclei have been tabulated and compared with the previously calculated values, if available. The effective rate or half-life calculated for a bare atom might be helpful to set a limit on the maximum enhancement due to bound state decay. Finally, beta(-) decay branching for a bare atom has been calculated. The changes in branching in a bare atom compared with that in a neutral atom and for the first time branching flip for a few cases have been obtained. The reason for this branching change has been understood in terms of Q values of the transitions in the neutral and bare atoms. Verification of this branching change or flip phenomenon in bare-atom decay might be of interest for future experiments.
