Fission probabilities ofAm242,Cm243, andCm244induced by transfer reactions

We have measured the fission probabilities of $^{242}\mathrm{Am},^{243}\mathrm{Cm}$, and $^{244}\mathrm{Cm}$ induced by the transfer reactions $^{243}\mathrm{Am}(^{3}\mathrm{He},^{4}\mathrm{He}),^{243}\mathrm{Am}(^{3}\mathrm{He},t)$, and $^{243}\mathrm{Am}(^{3}\mathrm{He},d)$, respectively. The details of the experimental procedure and a rigorous uncertainty analysis, including a correlation matrix, are presented. For $^{243}\mathrm{Cm}$ our data show clear structures well below the fission threshold. To our knowledge, it is the first time that these structures have been observed for this nucleus. We have compared the measured fission probabilities to calculations based on the statistical model to obtain information on the fission barriers of the produced fissioning nuclei.
