WebWe know that isotopes are atoms with the same atomic number but different mass numbers due to a different number of neutrons. The mass number of an element is a whole number whereas the actual mass of an atom is not a whole number except for carbon-12. For example, the atomic mass of Lithium is 6.941 Da. WebAB - Relativistic mean-field calculations have been carried out for Li isotopes using the non-linear Lagrangian parameter set NL2. Both spherically symmetric and axially deformed cases are considered. The binding energies, charge, neutron and matter rms radii, one and two neutron separation energies have been calculated.
