“…7 to permit a direct comparison with 19 F + 12 C). The large NOC value for 19 F + 12 C [29] (almost order of magnitude bigger) is consistent with the fact that essentially no resonances have been observed in this system [43,44]. This was confirmed by the times scale measurements of Suaide et al [45] who found that fusion-fission (with high NOC values), a very slow mechanism, is more competitive than a faster process such as orbiting (with small NOC values) in 19 F + 12 C. It is worth noting from Table I that CASCADE predicts almost identical fusion-fission cross section for both reactions at E * = 60 MeV.…”

Fragment emission studies of the16O+12Creaction

“…Though for the present reaction the values of l gr (h), at the energies 117, 125, 145, and 160 MeV are 27, 28, 31, and 33, respectively, are larger than the value (l gr = 25(h)) at which the NOC for the system 16 O + 12 C shows a characteristic minimum, the corresponding NOC are much less compared to those for the other two nearby systems viz. 18 O + 10 B and 19 F + 12 C. The large NOC values for 18 O + 10 B and 19 F + 12 C systems are in consistent with the fact that no resonances have been observed for this systems [27,34,35]. In a detailed study of the energy damped yield of the binary fragments emitted in the reactions 19 F + 12 C and 18 O + 10 B, it was observed that fragments were originated from FF rather than through deep-inelastic orbiting processes, which is also in agreement with the observation of large NOC for these systems [10,36].…”

Role of the number of open channels in the dynamics of the dinucleus binary decay

“…Entrance channel effects have been experimentally investigated in the N+ 0 and the C+ F reactions leading to the P composite system [87]. In agreement with the NOC calculations, the resonant behavior present in the N+ 0 collision [88,89] tends to disappear with the less surface-transparent C+ F reaction, similarly to loB+180…”

“…The resonance cross sections have a strong dependence not only on the mass and charge of the colliding nuclei but also on their nuclear structure and on the mass asymmetry of the entrance channel, as shown for the s~P composite system [87,89]. This last eff'ect is evident for the ssNi CN which presents the most intense resonant behavior in the~s Si+2sSi collision [17].…”
