delayed proton decay of 24Si

A novel experimental approach has been employed for the measurement of $\ensuremath{\beta}$-delayed protons from ${}^{24}\mathrm{Si}$ produced via the fragmentation of a ${}^{28}\mathrm{Si}$ beam with an energy of 100 MeV/nucleon. The secondary beam of ${}^{24}\mathrm{Si}$ was separated by the projectile fragment separator RIPS at RIKEN and was implanted in a 2.6 $\ensuremath{\mu}\mathrm{m}$ aluminum foil placed parallel to a gas-$\ensuremath{\Delta}E$ and silicon-$E$ detector telescope for the measurement of delayed protons. The above arrangement has led to a very clean, $\ensuremath{\beta}$-ray background free delayed proton energy spectra and a few new proton peaks could be identified from the decay of ${}^{24}\mathrm{Si}.$
