Systematic study of probable projectile-target combinations for the synthesis of the superheavy nucleus120302

Abstract

Probable projectile-target combinations for the synthesis of superheavy element 302 120 have been studied taking Coulomb and proximity potential as the interaction barrier. The probabilities of compound nucleus formation, P CN for the projectile-target combinations found in the cold reaction valley of 302 120 are estimated. At energies near and above the Coulomb barrier, we have calculated the capture, fusion and evaporation residue cross sections for the reactions of all the probable projectile-target combinations so as to predict the most promising projectile-target combinations for the synthesis of SHE 302 120 in heavy ion fusion reactions. The calculated fusion and evaporation cross section for the more asymmetric ("hotter") projectile-target combination is found to be higher than the less asymmetric ("colder") combination. It can be seen from the nature of quasi-fission barrier height, mass asymmetry, probability of compound nucleus formation, survival probability and excitation energy,

Influence of proton shell closure on the evaporation residue cross sections of superheavy nuclei

“…Inspired by these abundant experimental data, many theoretical models have been presented [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. To precisely reproduce the experimental data, all models meet the same problems; the survival probability of the compound nucleus against fission in the deexcitation process is considered to be one of the crucial factors.…”

Signatures of elongated and compact configurations in the fusion barrier distribution of deformed nuclei

“…The proposed 294−304 120 isotopes were estimated to exhibit longer half-lives over the anticipated not yet synthesized isotopes of the Z = 120 elements [60], which are suggested to be an example of the reactions that can possibly be examined to synthesis 297−301 120 is the fusion of 50 Ti with 251 Cf [61][62][63]. Also, the fusion of 50 Ti with 249 Cf and 249 Bk were suggested to be examined for synthesis of the prospective 295−299 120 and 295−299 119 isotopes [61,62,64].…”

The orientation dependence of the Coulomb barrier height V B (MeV) is displayed for the scattering potentials of 50 Ti with the three 251 Cf, 249 Cf and 249 Bk nuclei in figure 7 interacting prolate deformed nuclei, which exhibit an almost orthogonal (θ ≈ 90°) compact configuration, where the surface area covered by the orientation angle is weighted in the averaging process by q sin .…”

The Probable Projectile-Target Reactions to Synthesize SHE 304–312,314124 and the Predictions of α Decay Chains

“…The entrance channel effects on capture cross-section, fusion probability, survival probability, and evaporation residue crosssection for the synthesis of SHE, Z = 119 and Z = 120, are done by Li et al, [19]. In our previous works [20][21][22][23][24], we have also studied the same effects and predicted the most probable combinations to synthesize Z = 114, Z = 116-120. Also, we have performed a number of studies on the decay properties of superheavy elements [25][26][27][28][29].…”
