Abstract
Very little is known about clustering in heavy nuclei and in particular the
interaction between the correlated cluster nucleons and remaining core nucleons. Currently
the phenomenological Saxon-Woods plus cubic Saxon-Woods core-cluster potential successfully
predicts the alpha decay half-life and energy band spectra of a number of heavy nuclei. This
model, however, lacks a microscopic understanding of clustering phenomenon in these heavy
nuclear systems. A fully relativistic microscopic formalism is presented, which generates the
core-cluster potential by means of the McNeil, Ray and Wallace based double folding procedure.
The core and cluster baryon densities are calculated by using a relativistic mean field approach.
The Lorentz covariant IA1 representation of the nucleon-nucleon interaction is folded with the
core and cluster densities. Theoretical predictions of the ground-state decay half-life and positive
parity energy band of 212Po are obtained with the relativistic mean field formalism and which
are compared to the results from the phenomenological Saxon-Woods plus cubic Saxon-Wood
core-cluster potential and microscopic M3Y interaction.
