| Research Abstract |
New shell model interactions which properly take into account important roles of the tensor force induced mainly by pion-exchnages are constructed. They can explain well new phenomena of exotic shell structure of nuclei, that is, shell evolutions such as changes of magic numbers toward drip lines and exotic electromagnetic transitions in neutron-rich nuclei. Strength distributions of spin dependent transitions are found to be modified by the new interactions. They are applied to neutrino-nucleus reactions in stars, and effects on nucleosynthesis (syntheis of Li, B and Mn etc.) during supernova explosions are examined.
