Si 25 and S 29 studied via single neutron knockout reactions

The $\ensuremath{\gamma}$-ray spectroscopy of $^{25}\mathrm{Si}$ and $^{29}\mathrm{S}$ has been performed using single neutron knockout reactions with intermediate energy beams of the exotic isotopes $^{26}\mathrm{Si}$ and $^{30}\mathrm{S}$. Two $\ensuremath{\gamma}$ rays have been observed in $^{25}\mathrm{Si}$ and three in $^{29}\mathrm{S}$. These are the first $\ensuremath{\gamma}$ rays observed in these two isotopes. These two nuclei appear to be well deformed, and possible future intermediate-energy Coulomb excitation measurements would confirm their rotational nature.
