Abstract

A single-channel alpha-particle plus core cluster model, based on the folding potential of Pal and Lovas (PL), is used to calculate the alpha-cluster states in 40Ca, 114Pd, 188Os and 238U. The PL potential parameters (V0 and R) were adjusted to give the best fit to the spectra of these nuclei. These potential parameters define an alpha-particle plus core (APPC) interaction which provides a theoretical representation of 40Ca, 114Pd, 188Os and 238U in terms of rotational spectra. The radius parameter (R) for the APPC interaction is found to vary as a linear function of the mass number A. When the APPC interaction is applied to 114Pd, the calculated spectrum is in reasonable agreement with the observed 0+, 2+, 4+ and 6+ spectrum. These results suggest the single-channel, alpha-particle plus core cluster model and the APPC interaction provide a reasonable description of the alpha clustering phenomena for nuclei with rotational or rotational-like spectra.
