Abstract
We report the study of the () reaction on , , and at MeV and on the application of the two-neutron-transfer sum rule of Bayman and Clement to these data. Analysis of the sum rule shows that the observed dramatic increase in cross sections as one goes from targets of to to and the nearly-as-dramatic decrease in cross sections reflect general features of the shell-model character of these nuclei. Application to the present series of nuclei shows that this two-neutron-transfer sum rule can be applied with nearly the same accuracy as the corresponding single-nucleon-transfer sum rules. The relationship between the shell-model and pairing-vibration () strengths is discussed.
