Studies of Transfer Reactions with Exotic Beams:. Superheavy Hydrogen 5H

Recently, in experiments with exotic nuclear beams, such a new step as investigations of transfer reactions was established. Here we present recent results of studies of transfer reactions with beams of ⁸He and ⁶He. The transfer reaction p(⁸He,d)⁷He has been studied by correlational measurements, and an excited state of ⁷He was observed. Most likely, it has a structure with a neutron in an excited state coupled to the ⁶He-core which itself is in the excited 2⁺-state. Experimental search for ⁵H has been performed in the reaction p(⁶He,²He)⁵H by detecting two protons emitted from the decay of ²He. A peak consistent with the ⁵H resonance at 1.7±0.3 MeV above the n+n+t threshold was observed, with a width of 1.9±0.4 MeV. The angular distribution of the p(⁶He,²He)⁵H reaction was measured as well as the energy correlation of two protons.
