Comparative study of the alpha decay of Hg isotopes using different forms of nuclear potentials La désintégration alpha des isotopes du mercure, à travers différents modèles de potentiel nucléaire

Alpha decay half-lives of 171-189Hg isotopes using Modified Gamow-like model and temperature dependent proximity potential

“…It should be noted that near double magicity of the parent nucleus 202 Hg (Z = 80, N = 122) was suggested in Ref. [28]. Figure 2 shows plots of the Q α values against neutron number for the Hg isotopes while the calculated temperature of the Hg plotted against the neutron number in Figure 3.…”

“…The new values for the parameters a, r 0 , and h in the modified Gamow-like model (MGLM2) were obtained through least squares fitting procedure. The values of the three adjustable parameters obtained for the Hg isotopes are r0 = 1.2457fm, h = 0.1891, a = −2.159 × 10 −3 (28) The database have been taken from the NUBASE2016 [34,35,36]. The reaction Q α value has been computed via [29]:…”

“…It should be noted these Hg isotopes were studied in Ref. [28] using about various proximity potential models. However, the authors considered experimental values of 171−177 Hg only.…”

“…The α-decay half-lives of some mercury isotopes have also been studied in Ref. [28] using about 25 different versions of the nuclear potential.…”
