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 O+ channel in Ne as well as the + channel in Be. The approximation is found to be reasonable to evaluate the RWA for states near the threshold energy and it is useful to estimate the -decay width of resonance states. The approximation is also applied to Li, and the partial decay width of the He()+ channel is discussed.
