Abstract
Proton radioactivity from deformed nuclei is described for the first time by a self-consistent calculation based on covariant relativistic density functionals derived from meson exchange and point coupling models. The calculation provides an important new test to these interactions at the limits of stability, since the mixing of different angular momenta in the single particle wave functions is probed.

The fast development of Radioactive Ion Beam (RIB) facilities, and new technologies on multi-particle detection, are leading to the production and detection for the first time in a laboratory of many nuclei far from stability, that should have been formed in the stellar synthesis of the elements
On the proton rich side of the nuclear chart, the observation and interpretation of proton radioactivity have been the only possibility to obtain information on the structure of proton drip-line nuclei, since this decay is the only feature that allows to select, in an experiment, drip-line nuclei from all the other nuclei produced in the reaction
