We propose helium–4 spallation processes induced by long–lived stau in supersymmetric standard models, and investigate an impact of the processes on light elements abundances. We show that, as long as the phase space of helium–4 spallation processes is open, they are more important than stau–catalyzed fusion and hence constrain the stau property. This talk is based on the work of ref.[1].
