| Research Abstract |
Since this year is the last year of the research project, we summarized the studies made until last year and also promoted some new works for the future.
(1)Study of ^<12>Be. (already published)
Like other Be isotopes, the ground and low-lying states are well described by molecular orbit picture. But some excited states have neutrons described well by the atomic-orbital picture
(2)Vanishing of the N=20 magic number. (to be published)
Neutron 2p2h structure is dominant for the ground states of ^<32>Mg and ^<30>Ne. In some excited states of ^<30>Ne, 4p4h structure is dominant which is related to α-^<16>O structure.
(3)Study of ^<32>S. (to be published)
Super deformed excited has ^<16>O-^<16>O molecular structure.
(4)Study of 44Ti (submitted)
Coexistence of super deformed bands and α-^<40>Ca stales is reproduced.
