Nuclear Energy Levels in the Region of the 28-Neutron Shell

Energy levels of the titanium nuclei of mass numbers 47, 48, 49, 50, and 51 have been obtained by measuring the ranges of proton groups from the reactions $\mathrm{Ti}\mathrm{}(d,p)\mathrm{}\mathrm{Ti}$. With the use of enriched isotopes, it has been possible to assign thirty observed $Q$ values to their proper reactions. Good agreement was found in most cases in which results of this study could be compared with the results of others.
