Theoretical studies of exotic drip-line nuclei, L. S. Ferreira, CFIF/ Instituto Superior Técnico, Lisboa − The observation of nucleon emission from drip-line nuclei has provided a unique possibility to probe nuclear structure at the extremes of stability. From proton radioactivity, an exotic decay from levels very low in the continuum, thanks to the high sensitivity of the decay rates to details of the nuclear wave function, one can identify the dominant proton orbital, and extract important information on the structure and symmetries of the nuclei involved.
use of recoil decay tagging technique, based on very selective
correlations between prompt γ-rays detected at target plane with
radioactive products, results in the observation of very fine
spectra of the
excited states of proton unbound nuclei. One can thus follow the
evolution of proton
orbitals towards the drip-line, and consequently the evolution of
structure and shape. In
talk, we will review the theoretical approaches developed by our
group to understand
the mechanisms of decay by one proton emission, and the structure
and shape of
exotic nuclei at the limits of stability.
