    "abstract": "Deformed states in $^{40}$Ca are investigated with a method of\nantisymmetrized molecular dynamics. Above the spherical ground state,\nrotational bands arise from a normal deformation and a superdeformation as well\nas an oblate deformation. The calculated energy spectra and $E2$ transition\nstrengths in the superdeformed band reasonably agree to the experimental data\nof the superdeformed band starting from the $0^+_3$ state at 5.213 MeV. By the\nanalysis of single-particle orbits, it is found that the superdeformed state\nhas particle-hole nature of an $8p$-$8h$ configuration. One of new findings is\nparity asymmetric structure with $^{12}$C+$^{28}$Si-like clustering in the\nsuperdeformed band. We predict that $^{12}$C+$^{28}$Si molecular bands may be\nbuilt above the superdeformed band due to the excitation of inter-cluster\nmotion. They are considered to be higher nodal states of the superdeformed\nstate. We also suggest negative-parity bands caused by the parity asymmetric\ndeformation.",
