Alpha and exotic cluster decay with a new single particle basis

Abstract

A single particle basis consisting of two different harmonic oscillator representations is introduced with the aim of studying microscopically alpha and cluster decay processes. A correct description of the wave functions at large distances is obtained within a minimal single particle basis. Experimental data corresponding to a large number of alpha decay transitions from even-even nuclei are well reproduced. Applications to 14 C decay from Ra isotopes are presented.
