Invited talk

Discrete gamma ray spectroscopy using large array of Compton suppressed high purity germanium detectors continues to provide new insights on the structure and dynamics of the nuclear systems. The Indian National Gamma Detector Array(INGA) is set up at TIFR-BARC accelerator facility at Mumbai, as a part of a collaboration between BARC, IUAC, SINP, TIFR, UGC-CSR-KC, VECC and different...

19. Superdeformed Band in Asymmetric N>Z Nucleus, 40Ar, and High-Spin Level Structures in A～40 Nuclei

Contribution talk

Nuclear superdeformation is a unique testing ground for the shell structure at extreme deformation. In the light mass region, superdeformed (SD) states were investigated along the N=Z line and a new ‘island’ of SD nuclei was found around A～40 nuclei (i.e., 36Ar[1], 40Ca[2], and 44Ti[3]). Presences of these SD bands indicate the SD shell gaps at N=Z=18, 20, and 22. To clarify the SD shell...

24. Quantal descriptions of Superdeformed states of Ca and Ar.

Contribution talk

By means of angular momentum projection, HFB states corresponding to SD states of Ca and Ar isotopes are quantized. Energy levels are calculated, and the relevant nuclear structure is analyzed from a dynamical point of view.

12. Coexistence of various rotational bands and alpha clustering in 42Ca

Dr Yasutaka TANIGUCHI (RIKEN Nishina Center for Accelerator-Based Science, RIKEN)

Contribution talk

Structures of low-lying states in 42Ca have been studied focusing on deformations and clustering using the antisymmetrized molecular dynamics and the generator coordinate method (GCM). Energy variation with constraints on quadrupole deformation parameter and inter-cluster distance between and 38Ar clusters obtain GCM basis, which have deformed and {38Ar cluster structures, respectively....
