    "abstract": "The spectral and statistical properties of nuclei $^{46}$V and $^{48}$Cr are\nstudied in the framework of nuclear shell model. A microscopical effective\nHamiltonian derived from the CD-Bonn \\textit{NN} potential is employed. The\ncalculations are preliminary results of a newly developed parallel shell-model\ncode. Calculations with the realistic \\textit{NN} interaction reproduce well\nthe ground-state rotational band and backbending phenomenon in $^{48}$Cr. A\nsudden alignment of all particles is seen above the backbend. The\nnearest-neighbour spacing distribution in $^{46}$V is presented and compared\nwith the predictions of random-matrix theory. Significant deviation from the\nsingle Gaussian-orthogonal-ensemble distribution is obtained, indicating that\nthe isospin-symmetry breaking is not so strong in the nucleus.",
