摘要：

The effective IBA hamiltonian is used to describe the low-lying spectra and electromagnetic properties of several series of even-even chains of isotopes and isotones. Applications are made to the Sm, U, Pt, Os and Ru chains of isotopes and to the following chains of isotones: ISO88 that includes Ba-144(56) Ce-146(58), Nd-148(60), Sm-150(62), Gd-152(64), Dy-154(66), Er-156(68) and Yb-158(70), Ba-146(56), Ce-148(58), Nd-150(60), Sm-152(62), Gd-154(64), Dy-156(66), Er-158(68) and Yb-160(70). For all the members of each chain, only one set of parameters of the effective hamiltonian is calculated by a least-squares analysis, making this a global study instead of a nucleus-by-nucleus zone. The model thus applied reproduces some 250 experimental energies with a r.m.s, deviation of about 100 keV. Electromagnetic transitions B(E2) are also calculated globally for each chain by fitting the experimental data of several types of transitions.
