Project description

Nuclear collective motion comprises situations in which many nucleons move together in either the excited state of a single nucleus, or a reaction situation between two or more nuclei. A basic, but entirely microscopic, approach to their theoretical study comes from the Time-dependent Hartree-Fock approach, which is a kind of mean-field approximation.  

This project involves developing the methodologies involved to study cases of experimental interest; ongoing projects include projecting out good quantum numbers on nuclei undergoing reactions to study fragment distribution, transfer probabilities and the development of isospin states following fission reactions. The project also considers the input to the calculations in terms of the model of the underlying nuclear force, to better understand how to pin this down through comparison of calculated observables with experiment, as a function of varying the nuclear force model. 

Students in the group have worked on a variety of projects, from nuclear forces, to vibrational excitation, fission, to more conceptual physical, mathematical or computational developments, according to each student. Those interested in a combined theoretical and computational project in nuclear physics should get in touch with Dr Stevenson, the supervisor as listed above.
