55. Recent physics highlights from MINIBALL at REX-ISOLDE

Dr Janne Pakarinen (CERN-ISOLDE)

30/06/2011, 13:30

Invited talk

The MINIBALL Ge-detector array at the REX-ISOLDE post-accelerator has been a workhorse in diverse nuclear structure studies over the past decade. In conjunction with particle detector arrays it has provided excellent in-beam data throughout the chart of nuclei, especially in Coulomb excitation and transfer reaction experiments. This talk is focused on recent physics highlights and will shed...

64. Location of the g9/2 orbit in neutron-rich Ca isotopes studied with the shell model

Contribution talk

The tensor force has been regarded as an importance ingredient that causes the evolution of the shell structure in exotic nuclei. From its point of view, the spin-orbit splitting decreases from the L-S closure to the j-j closure. It is thus predicted that a new N=34 magic number would arise in Ca isotopes according to high location of the f5/2 orbit. In Ca isotopes, while the location of the...

31. Study of Neutron-Rich Mg Isotopes through $\beta$-decay of Spin-Polarized Na Isotopes

Mr Kunihiko Tajiri (Dep. of Phys., Osaka Univ., Osaka, Japan)

Contribution talk

The exotic structure of neutron-rich nuclei around “island of inversion” characterized by the disappearance of the neutron magic number $N$ = 20 has been attracting attention. However, most of the information on the excited states of these nuclei, such as spin and parity and so on, has not been known well. We have developed a new method to unambiguously determine the spin-parities of daughter...

18. Isospin breaking effects in 51Co, 48Fe, and their mirror partners

Dr Paul Davies (University of York)

30/06/2011, 14:40

The measurement of mirror energy differences between excited states in pairs of nuclei, with the same mass but interchanged proton and neutron numbers, provides a unique test of the nucleon-nucleon interaction. The origin of these energy differences lies in the isospin breaking components of the nucleon-nucleon interaction (see for example the review by Bentley and Lenzi [1] and references...

47. Extrapolation method in the Monte Carlo Shell Model and its application to medium heavy nuclei

Dr Noritaka Shimizu (Center for Nuclear Study, University of Tokyo)

30/06/2011, 15:00

Contribution talk

We recently developed the extrapolation method using the energy variances in the Monte Carlo Shell Model. By using this framework, we can precisely evaluate energy eigenvalues and other physical quantities of the system whose degree of freedom is so large that the conventional diagonalization method is not feasible. It also enables us to perform shell-model calculations in medium heavy...
