    "abstract": "The mechanism of backbending in $^{48}$Cr is investigated in terms of the\nProjected Shell Model and the Generator Coordinate Method. It is shown that\nboth methods are reasonable shell model truncation schemes. These two quite\ndifferent quantum mechanical approaches lead to a similar conclusion that the\nbackbending is due to a band crossing involving an excited band which is built\non simultaneously broken neutron and proton pairs in the ``intruder\u0027\u0027 subshell\n$f_{7/2}$. It is pointed out that this type of band crossing is usually known\nto cause the second backbending in rare-earth nuclei.",
