Superdeformed nuclei and their decay: challenging nuclear models and probing quantum tunnelling. Nuclear superdeformation, where the atomic nucleus adopts an elongated, ellipsoidal shape and can undergo rapid rotation, offers a fascinating opportunity to study quantum mechanical effects in a system where single-particle and collective regimes overlap. The superdeformed shape itself is a spectacular example of collective motion in a mesoscopic system, while the rapid change to a sperhical shape ....Superdeformed nuclei and their decay: challenging nuclear models and probing quantum tunnelling. Nuclear superdeformation, where the atomic nucleus adopts an elongated, ellipsoidal shape and can undergo rapid rotation, offers a fascinating opportunity to study quantum mechanical effects in a system where single-particle and collective regimes overlap. The superdeformed shape itself is a spectacular example of collective motion in a mesoscopic system, while the rapid change to a sperhical shape is an excellent example of quantum-assisted tunnelling. The results of this project will shed light on this important process and provide a stringent test of our understanding of the nucleus.Read moreRead less
Exploiting new breakthroughs in understanding nuclear fission. This project aims to characterise and quantify the quantum energy levels crucial in determining the mass and energy distributions of nuclear fission products, which recent results show are far from understood. Combining new techniques and concepts, distributions will be measured down to the fission barrier energies, maximising sensitivity to quantum effects.

Structure of Hadronic Excitations from Lattice Quantum Chromodynamics. Quantum chromodynamics describes the fundamental strong interactions between quarks and gluons as they compose hadrons such as the proton or neutron.

Electromagnetic structure of hadronic excitations from lattice quantum chromodynamics. Just as quantum electrodynamics describes the quantum mechanical excitation spectra of atomic systems, quantum chromodynamics (QCD) describes the excitation spectra of quark and gluon systems, such as the proton. This project will resolve the internal structure of the low-lying excitations of QCD, as being investigated at international facilities.
