Estimation of the 3-body force, ΔU, in ^<11>Li due to excitation of the ^9Li core is discussed. An expression of ΔU up to second order in non-diagonal elements of the interaction potentials is derived, and a very simple expression is obtained in closure approximation. A formula is given for the estimate of an upper limit of the energy shift due to ΔU.

Effects of neutron halo on the meson exchange current (MEC) contributions to the magnetic moment of ^<11>Be (1/2^+_<g.s.>) as well as those on a GT β transition ^<11>Li (3/2^-)→^<11>Be (1/2^-, 0.32 MeV) are investigated. The halo is found to reduce considerably the MEC contributions to the magnetic moment of ^<11>Be_<g.s.>. The halo as well as MEC are also found to be important to reduce deviations from the observed log ft value of the GT transition.

The quadrupole giant resonances in the oxygen isotopes have been investigated in terms of the Hartree-Fock calculations and the random-phase approximations. It has been seen in the nuclei with neutron skin that the average excitation energies are lowered from the standard mass number dependence and that the neutron mode excitations lie below the main isoscalar excitations. It has also been seen that there is no proton-neutron correlation in the neutron mode excitation. The RPA calculation with the bound state approximation has the shortcoming that it may not be able to reach the convergence for the unstable nuclei. Therefore, there is a need for more sophisticated method (continuum RPA, for example) to compare the results, though an overview of the characteristics of the neutron skin must be unchanged.

Some properties of neutron-rich light nuclei are investigated in terms of the axially symmetric deformed Woods-Saxon potential. The effects of nuclear size become prominent in light nuclei and we discuss some of such effects. For the spherical potential, it turns out that the diffuseness parameter a of light nuclei is smaller than that of heavy nuclei. The proton-neutron symmetry potential in light neutron-rich nuclei is more important than that in heavy nuclei. Finally, the effects of deformation in light nuclei are investigated. As results of the present discussions, some observed characteristic properties of the anomalous ground state of ^<11>Be are reproduced by the deformed Woods-Saxon potential.

The electric magnetic property of light neutron-rich nuclei is studied with Antisymmetrized version of Molecular Dynamics(AMD). Systematical study about nuclei with 10 neutrons (from ^<14>Be to ^<20>Ne) has been made, and the structure change is discussed. We compare the calculated results to the observed magnetic moments of O,F,Ne and suggest that it is important to treat the intrinsic spin function for each single particle as the variational value. We discuss briefly about the electric quadrupole moments of B isotopes.

We discuss the reliability of a recent global nuclear-structure calculation in regions far from ft stability. We focus on the results for nuclear masses, but also mention other results obtained in the nuclear-structure calculation, for example ground-state spins. We discuss what should be some minimal requirements of a nuclear mass model and study how the macroscopic-microscopic method and other nuclear mass models fullfil such basic requirements. We study in particular the reliability of nuclear mass models in regions of nuclei that were not considered in the determination of the model parameters.

We study the reactions between a stable nucleus and an unstable nucleus with the neutron skin using the 2-dimensional TDHF calculation, focusing on the nucleon transfer and the fusion reactions. It is shown that the neutrons in the unstable nucleus are transferred to the stable one and the protons in the stable one are transferred to the unstable one. It is considered that such transfers are caused by the difference of the Fermi energy between these nuclei. However, for fusion reaction, a prominent effect of the neutron skin has not been seen.

We present a new method for macroscopic quantum tunneling based on the path integral approach. In this method the effects of environment on tunneling rate of the macroscopic degrees of freedom is given by the decrease of the norm of the environmental wave function. Comparison with the direct calculation of the coupled channels equations verifies the accuracy of this method. It is also shown that our norm factor is closely related with a dissipation factor obtained by using the instanton method for the Caldeira-Leggett lagrangian.
