Lifetime Measurements of Tagged Exotic‐ and Unbound Nuclear States

A new Differential Plunger device for measuring pico‐second lifetimes of Unbound Nuclear States (DPUNS) is being built at The University of Manchester. DPUNS has been designed to work with alpha‐, beta‐ and isomer‐tagging methods using the existing JUROGAM II—RITU—GREAT infrastructure at the University of Jyvaskyla, Finland. The importance of proton emission from nuclei is that it provides valuable nuclear‐structure information as direct input to nuclear models beyond the drip line. New experimental data beyond the drip line can provide new extensions to these models especially with the possible coupling of weakly bound and unbound states to the continuum. The results of the first experiments to measure lifetimes of unbound nuclear states with this method was discussed along with possible future experiments which can be addressed with DPUNS using proton‐, isomer‐ and alpha‐tagging.
