Phys. Rev. C 78, 044001 (2008) [8 pages]Experimental study of resonance states in 7H and 6HReceived 3 July 2008; published 10 October 2008 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 0.57-0.21+0.42 MeV above the 3H+4n threshold with a width of 0.09-0.06+0.94 MeV. The 6H system was formed at 2.91-0.95+0.85 MeV with a resonance width of 1.52-0.35+1.77 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. © 2008 The American Physical Society URL:
