S. Liran et al., Semiempirical shell model masses with magic number Z=126 for translead elements with N <= 126 - art. no. 017302, PHYS REV C, 6301(1), 2001, pp. 7302
A semiempirical shell model mass equation based on magic number Z = 126 and
applicable to translead elements with N less than or equal to 126 is prese
nted. For alpha -decay energies the equation is shown to have a high predic
tive power and an rms deviation from the data of about 100 keV. The rms dev
iations for masses and other mass differences are between about 200 and 300
keV.
