The optimized model parameters for each nucleus was adjusted by fitting procedure using a computer simulated search program in order to describe the gradual change in the structure as neutron number varied and to reproduce the properties of the selected reliable state of positive parity excitation ([MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]) and the two neutron separation energies of all isotopes in each isotopic chain.
The systematics of the excitation energies of the low-lying states as a function of neutron number changing from 84 to 100 in the even-even lanthanides Nd/Sm/Gd/Dy isotopes in the mass region 144-166 and the actinide Th/U isotopes in the mass region 224-238 are presented in Figures (1,2).
Based only on the composition of the atom electron shells, it was possible to determine the nuclei binding energies, the nucleus neutron numbers, to reveal the important features of nuclei.
