    "abstract": "The nucleus $^{44}$Ti has low-lying levels of various kinds of mutually very\ndifferent nuclear structure displaying the richness of the nuclear many-body\ndynamics. It is shown that the deformed-basis antisymmetrized molecular\ndynamics by the use of the Gogny D1S force reproduces successfully and\nunifiedly two types of coexistence phenomena in $^{44}$Ti. Namely, on one hand,\nthe coexistence of the mean field structure and the cluster structure is\nconfirmed by verifying the normally deformed structure of the $K^\\pi$=$3^-_1$\nband with a 1-particle-jump intrinsic configuration and the $\\alpha + ^{40}$Ca\ncluster structure of the $K^\\pi$=$0^-_2$ band. The mixed character of the\nmean-field-like structure and the $\\alpha + ^{40}$Ca cluster structure of the\nground band is also shown. On the other hand, the coexistence of the normal\ndeformed mean field and the superdeformed mean field is confirmed by verifying\nthe triaxial superdeformation of the $K^\\pi$=$0_2^+$ band and the\n$K^\\pi$=$2^+_1$ band which has a 4-particle-jump intrinsic configuration. Good\nreproduction of the experimental data is shown for many kinds of quantities\nincluding the energy spectra, electric transition rates, alpha spectroscopic\nfactors. Preliminary discussions are given on the existence of hyperdeformed\nexcited states, the relation between superdeformation and clustering and so on.",
