- spectroscopy of $^{261}$ Db, the element 105, was performed for the first time, and the first experimental information on the proton configuration of the ground state of $^{261}$ Db was obtained. Non observation of and X rays following its decay indicates that the decay of $^{261}$ Db directly populates the 7/2 $^{-}$ [514] ground state or the 1/2 $^{-}$ [521] isomeric state in the daughter nucleus $^{257}$ Lr, and does not populate the 9/2 $^{+}$ [624] excited state. This result indicates that the proton configuration of the ground state of $^{261}$ Db should not be the theoretically predicted 9/2 $^{+}$ [624], but the 7/2 $^{-}$ [514] or 1/2 $^{-}$ [521].

We have numerically performed three dimensional calculation of inhomogeneous low-density nuclear matter in beta-equilibrium without any assumption on the geometry, and explored the structures and its properties. We have observed two type of nuclear pasta with different crystalline structures. One is a face-centered cubic lattice and another is a body-centered cubic lattice. So far, it has been regarded that there appears only a body-centered cubic. But in our self-consistent calculation with non-uniformity of electrons, ground-state matter has lattice structure of not only a body-centered cubic but also a face-centered cubic. We also calculated the shear modulus of neutron star crust matter using three-dimensional data we obtained. Because of the Coulomb screening, shear modulus have lower value than previous one.
