Experimental study of resonance states in 7H and 6H

Abstract : The 7H and 6H nuclear systems were investigated via transfer reactions with a 8He beam at 15.4A MeV impinging in a 12C target. The experimental setup allowed a complete reconstruction of the reaction kinematics with the MAYA gas detector, based on the active-target concept, where the carbon atoms of the filling isobutane played also the role of reaction target. The 7H resonance was observed at 0.57+0.42 −0.21 MeV above the 3H + 4n threshold with a width of 0.09+0.94 −0.06 MeV. The 6H system was formed at 2.91+0.85 −0.95 MeV with a resonance width of 1.52+1.77 −0.35 MeV. These results show the availability of nuclear structure information well outside the bounding limits, resulting in an extraordinary input to improve the present models and understanding of nuclear matter.
