    "abstract": "The ground state properties of even mass Cr and Fe isotopes are studied using\nthe generalized hybrid derivative coupling model. The energy surface of each\nisotope is plotted as a function of the mass quadrupole moment. The neutron\nnumbers N=20 and N=40 are seen to remain magic numbers but N= 28 and 50 are\npredicted to be non-magic. The neutron number N=70 turns out to be a magic\nnumber according to the present calculation. In all the isotopes studied the\ncalculated binding energy values are less than those obtained from experiment\nwhile the deformation is in better agreement.",
