Penetration factor in deformed potentials: Application toαdecay with deformed nuclei

Predictions of α decay half-lives for even–even superheavy nuclei with 104 ≤ Z ≤ 128 based on two-potential approach within cluster-formation model

“…[40][41][42] For SHN, α decay as a dominant decay mode can provides abun-dant nuclear structure information such as the nuclear shell structure, properties of ground state and so on. [43][44][45][46][47][48][49][50][51][52] Up to now, various theoretical models, such as cluster model, 53 generalized liquid drop model, 54 fission-like model 55 and so on, have been used to study the α decay half-lives. These models can reproduce the experimental α decay half-lives well.…”

“…Recently, superheavy element Z = 118 has been synthesized in the laboratory by 48 Ca-induced hot fusion reactions with actinide Cf target. 3,7 Many laboratories are trying to synthesize the new elements such as Z = 119, Z = 120 and so on.…”

Alpha-decay of deformed superheavy nuclei as a probe of shell closures

“…The renormalization factor λ(θ), introduced to the nuclear part of the folding potential is determined separately for each emission angle of α-particle by applying the Bohr-Sommerfeld quantization condition [9,36,37],…”

Systematic research on α-decay rates of spherical and deformed nuclei

“…In this case, the α-particle emission in each orientation θ is considered and the partial width Γ (θ ) is calculated as in the spherical case. Then the decay width is obtained by averaging Γ (θ ) along the orientation θ [61,75,74,76],…”
