MICROSCOPIC CALCULATION FOR ALPHA-EMISSIONS AND HEAVIER CLUSTER-EMISSIONS FROM PROTON RICH BA AND CE ISOTOPES

We present a completely microscopic approach for obtaining the preform ation factors and the decay of alpha C-12, and O-16 cluster decays. We start from realistic single particle Woods-Saxon wave functions and i nclude a large space BCS-type configuration mixing. A pairing interact ion acting among valence particles, placed above double magic core, wa s considered. The penetrability is evaluated within the WKB approximat ion. The model predictions are also checked for some well-known alpha and C-14 decays from even-even nuclei.
