Cluster radioactivity with effects of deformations and orientations of nuclei included

Clustering effects and decay analysis of the light-mass N=Z and N≠Z composite systems formed in heavy ion collisions

“…[11]). In the following, we have further highlighted the significance of an appropriate δ(T) in the present calculations while comparing the clustering effects in the N=Z, 20 Ne * , 28 Si * (or α conjugate) and N =Z, 21,22 Ne * (or non-α conjugate) nuclear systems (refer to Fig. 3, discussed in detail in the next section).…”

“…It may be reminded here that the DCM has been applied successfully to study the decay of light mass compound systems 28 [23,[25][26][27]. Also, the DCM explains successfully the fragments emission/ decay characteristics of medium, heavy and super-heavy compound systems.…”

“…The DCM is an extended version of preformed cluster model (PCM) of Gupta and collaborators to study the excited state decay of compound systems. The cluster radioactivity, the manifestation of clustering in the nuclei, has been studied successfully within the formalism of the PCM [28]. Within the PCM, the cluster emission of mass varying from 12 C to 34 Si in cluster radioactive decay process of nuclei in the trans-lead mass region, have been examined with inclusion of quadrupole and higher order deformations and non-compact orientations.…”

“…The cluster states are probed experimentally through the quasi-elastic scattering, transfer or the cluster knockout reactions and electromagnetic transitions [6]. The cluster structures have been studied experimentally in isotopes of Be and B, 18 O, 20,21,22 Ne, 24 Mg, 28 Si, 32 S, 40 Ca [7,8]. Moreover, experimentally, Rogachev et al [7] have worked out successfully on the prediction of α+np+α clustering for N =Z, 10 B nucleus.…”

“…In the present work, within the QMFT, we have investigated for α-clustering in light mass N=Z and N =Z nuclear systems 20 Ne * , 28 Si * and 21,22 Ne * , respectively, in their intrinsic excited state at resonant state energies corresponding to the 4α, 16 O cluster and non-α cluster 14 C (from 22 Ne * N =Z composite system only), given by the Ikeda diagrams. It may be pointed out here that we have confined ourselves to the resonant state energies of these nuclear systems, corresponding to 16 O and 14 C (from 22 Ne * ) clusters, only to explore the effect of pairing strength in the liquid drop energies on clustering.…”
