“…We have found that the experimental data could be nicely reproduced by taking into account five resonances with spins 2, 4, 6, 7, and 8. These states, together with resonances observed previously in the 20 Ne + 16 O reactions [44][45][46], determine a rotational band. Its moment of inertia is very close to that of a hyperdeformed band, provided by α-cluster [49] and Nilsson [30] calculations.…”

Fifteen strongly oscillating angular distributions of the elastic scattering of 12 C + 24 Mg at energies around the Coulomb barrier (E c.m. = 10.67-16.00 MeV) are reproduced by adding five Breit-Wigner resonance terms to the l = 2, 4, 6, 7, and 8 elastic S matrix. The nonresonant, background elastic scattering S matrix S 0 l is calculated using the São Paulo potential. The J = 2, 4, 6, 7, and 8h molecular resonances fit well into a rotational molecular band, together with other higher lying resonances observed in the 16 O + 20 Ne elastic scattering. We propose that the presently observed, largely deformed molecular band corresponds to the hyperdeformed band, which has been found previously in α-cluster calculations, as well as in a new Nilsson model calculation. Systematic study of its possible clusterizations predicts the preference of the 12 C + 24 Mg and 16 O + 20 Ne molecular structure, in accordance with our present results.

“…= 90° excitation functions which are out of phase with one another and so allow one to distinguish the sign of the parity-dependent term. One system for which this situation may occur is 160+20Ne (Schimizu et al 1983 for which the elastic scattering at backward angles is not only considerably larger than for 160+24Mg elastic scattering but also exhibits gross structures as a function of energy, unlike 160+24Mg.…”

“…(MeV) The parameters of the absorptive potential were then determined by least-squares fitting of angular distributions at 27·8 and 36· 1 MeV for which both forward and backward angle data are available Siwek-Wilczynska et al 1974). The latter angular distribution comprises forward angle data at 36·0 MeV and backward angle data at 36· 2 MeV.…”

The e C.m. = 90· excitation function for 16 0 + 24Mg elastic scattering, which is only sensitive to even partial waves, has been measured for energies 31·6..;; E c . m . ..;; 45·2 MeV in an attempt to resolve an uncertainty in the sign and magnitude of a proposed parity-dependent term in the 160_24Mg interaction. The data have been analysed by an optical model potential, which includes both a real parity-dependent interaction and an angular momentum-dependent absorptive term. Both the measurements and calculations show some structure but, since this does not correlate with the energies of the even shape resonances in the 160_24Mg interaction, no conclusion can be drawn concerning the sign and magnitude of the parity dependence of the 160_24Mg potential.

“…In A = 36 system resonances have been observed through the studies of Z4Mg(lZC, 4He)3ZS reaction [5], and of Z4Mg + l zC and 16 0 + ZONe elastic and inelastic scattering [6,7]. A recent experimental investigation [8] of Z~ lzc)zgMg and Z~ 2~…”

“…The resonant structures in 2~ lzc)zgMg and Z~ 2~ excitation functions were located by calculating the corresponding deviation functions [8]. From the analysis of the data the authors obtained a value of >0.95 for the fraction of cross section contributed by direct reaction (non-compound) by assuming the number of effective channels to be one [8].…”
