The combined dinuclear system (DNS) and statistical model implanted in KEWPIE2 have been used to study the prospects for synthesis of a superheavy element (SHE) with $Z=119$ $^{54}$Cr+$^{243}$Am fusion reaction. method calculation has verified by description evaporation residue cross sections measured $^{48}$Ca+$^{243}$Am calculated results partial total complete fusion, quasifission, fast fission residues formation both reactions are discussed.
The incomplete fusion has been proved as the formation and emission of $\alpha$ particle by increase in rotational energy very mass-asymmetric dinuclear system. results system model have confirmed that heavy-ion collisions occurs at a large orbital angular momentum ($L > 30 \hbar$) due to strong intrinsic barrier.
To disentangle the role of shell effects and dynamics, fission fragment mass distributions 191Au, a nucleus in newly identified island asymmetric sub-lead region, have been measured down to excitation energy ≈20 MeV above barrier via two different entrance channels, viz. 16O+175Lu 37Cl+154Sm reactions. Apart from having signature both cases, clear experimental evidence quasifission has observed Cl induced reaction, that also substantiated by theoretical calculations. This crucial along with...
Deformed even–even nuclei with quadrupole and octupole deformations are investigated on the basis of a nonadiabatical collective model. It is shown that model satisfactorily describes energy levels yrast first nonyrast bands alternating parity in rare-earth 150 Nd , 152, 154 Sm Gd 156 Dy 162, 164 Er actinides 232, 234, 236, 238 U . In 156, 158 224 Ra 228 Th 240 Pu second also described. The structure considered alternating-parity examined terms odd–even staggering diagrams.
The energy levels of excited states ground state, β- and γ-bands the lanthanide actinide even–even nuclei have been studied within Davydov–Chaban model (for three different types potential β-deformations) approximations for a small free triaxiality. It is shown that approximation with triaxiality better describes spectrum collective considered nuclei.
The ∆I = 1 "staggering" effect is investigated in the energy spectrum of positive and negative parities yrast band even-even actinide nuclei. described by formula proportional to discrete approximation fourth-order derivative function ∆E(I). It shown that characterized "zigzag" behavior does not vanish within observed range angular momenta.
The incomplete fusion has been proved as the formation and emission of $α$ particle by increase in rotational energy very mass-asymmetric dinuclear system. results system model have confirmed that heavy-ion collisions occurs at a large orbital angular momentum ($L > 30 \hbar$) due to strong intrinsic barrier.
On the basis of Davydov–Chaban model, we study evolution changes in spectrum levels excited states for ground-, β, and γ bands even-even nuclei neutron chains with N = 96, 98, 100. The energy these are considered low intermediate spins. It isshown that model describes satisfactorily above-mentioned chains.
