The two-proton radioactivity of Fe-45 was studied experimentally with a time projection chamber. The aim of the experiment was the reconstruction of the proton tracks in three dimensions. Energy and angular correlations have been determined and the data are compared with theoretical models, in particular with a three-body model. Moreover, the decay of Cr-43 was studied and beta-delayed one-, two- and three-proton emission could be established. The correlations observed for beta-delayed two-proton emission favour a sequential emission. Finally, beta-delayed two-proton emission was observed for the first time for Ni-51.
