NUCLEAR STRUCTURE ¹⁴⁰Ce, ^142,144Nd, ^144,146,148Sm, ¹⁴⁶Gd, ^148,150,152Dy, ^150,152,154Er, ^{152,154,156,158}Yb, ¹⁸²W, ^184,186Os, ^{178,180,182,184}Pt, ^{182,184,186,188,190,206}Hg, ^{190,192,194,196,198,200,202,204,206,208,210,212,214}Pb, ^{200,202,204,206,208,210}Po, ^{202,204,206,208,210,212,218,220,222}Rn, ^{208,210,212,214,220,222,224,226,228}Ra, ^228,230,232Th, ^234,236,238U, ^{238,240,242,244}Pu, ^{242,244,246,248}Cm, ^{242,244,246,248,250,252}Cf, ^248,250,252Fm, ^252,254No, ²⁵⁶Rf, ^{260,262,264,266}Sg, ²⁶⁶Hs, ^282,284Cn, ^286,288Fl, ²⁹⁰Lv; calculated rms charge radii, charge distribution using the generalized density dependent cluster model (GDDCM). A formula derived from Wentzel-Kramers-Brillouin (WKB) barrier penetration probability is proposed to calculate nuclear charge radii from the experimental α-decay energies and half-lives. Comparison with experimental data.
