已测量 ${}^{28}\mathrm{Si}{+}^{28}\mathrm{Si}$ 的片段-片段-$\ensuremath{\gamma}$ 重合，其能量对应于 ${}^{56}\mathrm{Ni} 中推测的共振总体。$片段角度分布以及 $\ensuremath{\gamma}$ 射线角度相关性表明出射碎片的自旋方向垂直于轨道角动量。这与 ${}^{24}\mathrm{Mg}{+}^{24}\mathrm{Mg}$ 和 ${}^{12}\mathrm{C}{+}^{12}\mathrm{C}$ 共振不同，表明两个扁圆 ${}^{28}\mathrm{Si}$ 原子核在赤道到赤道分子构型中相互作用。
Fragment-fragment-$\ensuremath{\gamma}$ coincidences have been measured for ${}^{28}\mathrm{Si}{+}^{28}\mathrm{Si}$ at an energy corresponding to the population of a conjectured resonance in ${}^{56}\mathrm{Ni}.$ Fragment angular distributions as well as $\ensuremath{\gamma}$-ray angular correlations indicate that the spin orientations of the outgoing fragments are perpendicular to the orbital angular momentum. This differs from the ${}^{24}\mathrm{Mg}{+}^{24}\mathrm{Mg}$ and the ${}^{12}\mathrm{C}{+}^{12}\mathrm{C}$ resonances, and suggests two oblate ${}^{28}\mathrm{Si}$ nuclei interacting in an equator-to-equator molecular configuration.
