Two proton radioactivity has been observed experimentally in the decay of 45Fe and 54Zn, and possibly of 48Ni. These first experiments only allowed for a limited comparison with theory: T1=2 and Q2P values. Experimental efforts have been achieved to measure dynamical observables in order to perform a more detailed study of the decay mechanism. Time projection chambers have been developped by groups of Bordeaux and Warsaw, and were successfully used at GANIL and MSU: those devices allowed for a first direct observation of the individual protons in the 2-proton radioactivity of 45Fe, and a first estimate of correlations of these protons.< Réduire
