Proton radioactivity

Proton radioactivity was discovered 35 years ago [1]. However, most of the data on over 40 proton-emitting states known to date were obtained recently using electromagnetic separators selecting recoiling fusion-evaporation reaction products. Observation of fine structure in proton emission [2-5] is particularly important since the deformation and structure of wave function of involved states can be determined from observed properties. Recent results obtained at Oak Ridge on rare-earth nuclei as well as the perspectives of further studies at the next generation radioactive ion beam facilities will be presented.\\ 1.
