Abstract
Our recent study of the $^{12}\mathrm{C}$${(}^{16}$O${,}^{8}$Be${)}^{20}$Ne and $^{12}\mathrm{C}$${(}^{16}$O,\ensuremath{\alpha}${)}^{24}$Mg reactions has led to the identification of two superdeformed shape isomeric states in $^{28}\mathrm{Si}$ at excitation energies of 43.7 and 46.2 MeV. We conjectured from this study that these resonances have structures which correspond to the secondary minimum with deformation parameters \ensuremath{\epsilon}=1.35 and \ensuremath{\gamma}=60\ifmmode^\circ\else\textdegree\fi{} according to Nilsson-Strutinsky calculations. We give arguments to show that this conjecture is more appropriate and consistent with the presently available evidence.
