New aspects in microscopic description of cluster decay processes

A single particle basis, consisting of two different harmonic oscillator representations, is introduced with the aim of studying microscopically 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 and 14C decay transitions from even-even nuclei are well reproduced. We also calculated spectroscopic factors, which are in good agreement with other calculations, where the Pauli principle was tacking into account properly. (authors)
