The decay of extremely neutron-deficient isotope 45Fe has been studied by using a new type of gaseous detector in which a technique of optical imaging is used to record tracks of charged particles. The two-proton radioactivity and the \beta -decay channels accompanied by proton(s) emission were clearly identified. For the first time, the angular and energy correlations between two protons emitted from the 45Fe ground-state were measured. The obtained distributions were confronted with predictions of a three-body model. Studies of \beta -decay channels of 45Fe provided first unambiguous evidence for the \beta -delayed three proton emission.
