Findings

$^{29}$F is a crucial marker for the island of inversion.

Recent measurements refine theoretical models of $^{29}$F.

Predictions for electromagnetic transitions are proposed for future experiments.

Abstract

The exotic, neutron-rich and weakly-bound isotope $^{29}$F stands out as a waymarker on the southern shore of the island of inversion, a portion of the nuclear chart where the effects of nuclear forces lead to a reshuffling of the single particle levels and to a reorganization of the nuclear structure far from stability. This nucleus has become very popular, as new measurements allow to refine theoretical models. We review the latest developments and suggest how to further assess the structure by proposing predictions on electromagnetic transitions that new experiments of Relativistic Coulomb Excitation should soon become able to measure.
