/ Abstract

The 7H resonance was produced via one-proton transfer reaction with a 8He beam at 15.4A MeV and a 12C gas target. The experimental setup was based on the active-target MAYA which allowed a complete reconstruction of the reaction kinematics. The characterization of the identified 7H events resulted in a resonance energy of 0.57(+0.42-0.21) MeV above the 3H+4n threshold and a resonance width of 0.09(+0.94-0.06) MeV.
