The structure of 13 C is studied with the semi-microscopic cluster model, 3α+n orthogonality condition model (OCM). The energy spectra of four 1/2- states and three 1/2+ states up to Ex ~ 13 MeV are successfully reproduced, in particular, three monopole transition strengths are in fair agreement with the observed ones. We discuss the cluster states and alpha particle condensation in the 1/2± states appearing around the 12 C +n, 9 Be +α and 3α+n thresholds.

Natural Way

We examine the extensive experimental data on partial half-lives for alpha-decay, and discuss some interpretations, with emphasis on the use of a simple three parameter cluster model. In this model, the alpha-particle moves in a potential well of fixed depth, in an orbit with a large value of a global quantum number. With the model parameters fixed at values consistent with those suggested by the underlying nucleon orbits, we obtain excellent agreement with the data, and reproduce the discontinuities associated with shell closure in a natural way.
