A review of experimental data obtained recently on proton-radioactive nuclei is presented. The highlights include the observation of fine structure in proton emission, for the decays of , and , and the studies of the excited states in proton-emitting nuclei. The observation limits are extended to few nanobarns cross-sections ( , and ) and few microsecond half-lives (e.g., ). Measured decay properties for thirty-nine proton-emitting ground and isomeric states contributed to the understanding of nuclear masses and evolution of single-particle states at and beyond the proton drip line. Experimental results have stimulated new theoretical approaches to proton emission and the structure of unbound narrow resonance states.
