“…7. Since the trend of the error looks approximately like c/A α we have determined the parameters of this assumed error function by use of the maximumlikelihood equations (15) and (16). We find c = 8.62 MeV and α = 0.57.…”

We tabulate the atomic mass excesses and nuclear ground-state deformations of 8979 nuclei ranging from 16 O to A = 339. The calculations are based on the finite-range droplet macroscopic model and the folded-Yukawa single-particle microscopic model. Relative to our 1981 mass table the current results are obtained with an improved macroscopic model, an improved pairing model with a new form for the effective-interaction pairing gap, and minimization of the ground-state energy with respect to additional shape degrees of freedom. The values of only 9 constants are determined directly from a least-squares adjustment to the ground-state masses of 1654 nuclei ranging from 16 O to 263 106 and to 28 fission-barrier heights. The error of the mass model is 0.669 MeV for the entire region of nuclei considered, but is only 0.448 MeV for the region above N = 65.

“…However, the maximum shell correction occurs at N = 178 instead of N = 184, which is consistent with the results in Refs. [30,33]. The analysis about the shift of the shell correction from N = 184 to N = 178 is given in Ref.…”

“…The analysis about the shift of the shell correction from N = 184 to N = 178 is given in Ref. [30]. According to the calculations, the superheavy nuclei 288,289 114 produced in the "hot" fusion reaction 48 Ca + 244 Pu [31] (the corresponding compound nucleus is 292 114) are close to this central area of the island.…”

“…Furthermore, the fission barriers of superheavy nuclei are roughly estimated by the values of the corresponding shell corrections [18,30] since in general the macroscopic fission barriers disappear at the superheavy region. It is known that the fission barrier is a very sensitive parameter in the realistic calculations for the survival probabilities of the produced compound nuclei.…”

Modification of nuclear mass formula by considering isospin effects

2010

View full text Add to dashboard Cite

We propose a semiempirical nuclear mass formula based on the macroscopic-microscopic method in which the isospin and mass dependence of model parameters are investigated with the Skyrme energy density functional. The number of model parameters is considerably reduced compared with the finite range droplet model. The rms deviation with respect to 2149 measured nuclear masses is reduced by 21%, falling to 0.516 MeV. The new magic number N = 16 in light neutron-rich nuclei and the shape coexistence phenomena for some nuclei have been examined with the model. The shell corrections of superheavy nuclei are also predicted.

“…7 The barrier against fission due to the macroscopic (liquid drop) properties of the nucleus decreases iapidly with increasing atomic number of the nucleus, to the point where, in the absence of shell effects, the heavy elements 2 would have extremely short spontaneous fission half-lives.…”
