摘要
利用轴向形变相对论平均场理论计算了A～ 5 0区的核基态性质 ,结果表明 ,在Fe同位素链中最稳定的核是56Fe和58Fe而不是通常的54Fe ;给出了46Cr,50 Fe和54N(N =Z - 2 ) ,45Cr,49Fe和53 Ni(N=Z - 3)核的质子和中子分离能 ,分析了它们的稳定性 .
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.
