Abstract：
We have carried out a study of A～50 isotopes in the framework of axially deformed relativistic mean-field theory. The ground-state properties of Ti(N22-32), Cr(N20-34) and Fe(N22-36) isotopic chains have been obtained. The separation energies of ⁴⁵Cr, ⁴⁶Cr,⁴⁹Fe,⁵⁰Fe,⁵³Ni and ⁵⁴Ni are given, from which we have investigated the stability of the nuclei. We concluded that there is little possibility to reach the high-spin states of ⁴⁵Cr and ⁴⁹Fe.
