    "abstract": "To study collective motion, the extended pairing plus $QQ$ force model\nproposed recently is applied to $A$=46, 48 and 50 nuclei in the $fp$ shell\nregion.\n  Exact shell model calculations in the truncated model space\n  $(f_{7/2},p_{3/2},p_{1/2})$ prove the usefulness of the interaction.\n  The simple model with the pairing plus quadrupole pairing plus $QQ$ force and\n$J$-independent isoscalar proton-neutron force reproduces unexpectedly well\nobserved binding energies, energy levels of collective (yrast) states and\nreduced $E2$ transition probabilities in $^{46}$Ti, $^{46}$V, $^{48}$V,\n$^{48}$Cr, $^{50}$Cr and $^{50}$Mn.\n  The correspondence between theory and experiment is almost comparable to that\nattained by the full $fp$ shell model calculations with realistic effective\ninteractions. Some predictions are made for energy levels and variations of\n$B(E2)$ in the yrast bands, in these nuclei. Characteristics of the interaction\nare investigated by comparing with the realistic effective interactions.",
