Spectroscopy and isospin symmetry studies of Exotic Neutron Deficient Nuclei
The study of competition between different nuclear shapes, and exploration of neutron-proton (np) correlations, along the line of nuclei with equal numbers of protons and neutrons (i.e., N=Z), is one of the crucial topics in contemporary nuclear structure (e.g. see Nature 469, 68.(2011)-Wadsworth). These studies push new directions in theory, and require innovative approaches to access these highly unstable nuclei. Using an approach not attempted before, we will use York’s developed expertise in knockout methodology (Phys. Rev. Lett. 111, 072501 (2013) - Bentley) to access a range of exotic predicted shapes in the N=Z nucleus 80Zr. We also aim to develop the “charge-exchange” reaction technique for accessing high-spin states along N=Z to probe the crucial np-correlations. In addition, we plan to use a new spectrometer at the University of Jyvaskyla, Finland, to study highly exotic proton rich systems near A=100 for the first time. The aim is to shed light on fundamental differences between the nn and pp interactions through comparisons of mirror nuclei.
The studentship has full funding for 3.5 years from STFC and the Department of Physics. As part of the programme of work there is the opportunity to spend an extended period overseas at either Michigan State University (USA) and/ or the University of Jyvaskyla (Finland), which have major accelerator laboratories.
Theoretical aspects of the above work are being undertaken by the new nuclear theory group in York under the direction of Prof J Dobaczewski. Although not essential, students who are interested in combining theoretical and experimental aspects of this work are welcome to apply.
