Spin Quantization in Heavy Ion Collision

We analyzed recent experimental data on the disassembly of $^{28}$Si into 7$\alpha$ in terms a hybrid $\alpha$-cluster model. calculated probability breaking several $\alpha$-like fragments for high $l$-spin values identical and non-identical spin zero nuclei. Resonant energies were found each $l$-value compared to other theoretical models. Toroidal-like structures revealed coordinate momentum space when averaging over many events at $l$. The transition from quantum classical mechanics is highlighted.
