For example, when an iron nucleus captures a neutron, it becomes a new isotope of iron, one whose proton number is 26--as is true for every iron atom--but whose neutron number has just increased by one (from, say, 30 to 31).
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 shape transitions versus neutron number is studied by the GCM.
All chains of lanthanides begins as vibrational with R(4/2) near 2.0 and move towards rotational (R(4/2) [right arrow] 3.33) as neutron number increases.
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.
