Scientific achievement
First exploration of rotational states in 19F through neutron transfer reactions on a short-lived 18F isomeric beam (about 160 ns half-life).
Significance and impact
Our work sets the basis for using transfer reactions on high-spin isomeric beams in order to probe otherwise inaccessible aspects of nuclear structure.
Research details
- The large spectroscopic strength observed for the 13/2+ state in 19F confirms the wave function purity expected in a maximally aligned terminating state
- The agreement between shell-model calculations and our experimental results reinforces the idea of a single-particle/collective duality in the descriptions of the structure of atomic nuclei
- ATLAS resources used: in-flight facility, HELIOS
