Approximation of reduced width amplitude and application to cluster decay width

Abstract

We propose a simple method to approximately evaluate reduced width amplitude (RWA) of a two-body spinless cluster channel using the norm overlap with the Brink-Bloch cluster wave function at the channel radius. The applicability of the present approximation is tested for the 16^{16}O+α\alpha channel in 20^{20}Ne as well as the α\alpha+α\alpha channel in 8^8Be. The approximation is found to be reasonable to evaluate the RWA for states near the threshold energy and it is useful to estimate the α\alpha-decay width of resonance states. The approximation is also applied to 9^9Li, and the partial decay width of the 6^6He(01+0^+_1)+tt channel is discussed.
