alpha particle momentum distributions from 12C decaying resonances

Abstract

The computed $\alpha$ particle momentum distributions from the decay of low-lying ${}^{12}$C resonances are shown. The wave function of the decaying fragments is computed by means of the complex scaled hyperspherical adiabatic expansion method. The large-distance part of the wave functions is crucial and has to be accurately calculated. We discuss energy distributions, angular distributions and Dalitz plots for the $4^{+}$, $1^{+}$ and $4^{-}$ states of ${}^{12}$C.
