Resonance State inH7
The existence of the $^{7}\mathrm{H}$ nuclear system was investigated via a one-proton transfer reaction with a $^{8}\mathrm{He}$ beam at $15.4\mathrm{A}\text{ }\text{ }\mathrm{MeV}$ and a $^{12}\mathrm{C}$ gas target. The experimental setup was based on the active-target MAYA which allowed a complete reconstruction of the reaction kinematics. The existence of the $^{7}\mathrm{H}$ was confirmed with the identification of seven events where the system was formed with a resonance energy of ${0.57}_{\ensuremath{-}0.21}^{+0.42}\text{ }\text{ }\mathrm{MeV}$ above the $^{3}\mathrm{H}+4n$ threshold and a resonance width of ${0.09}_{\ensuremath{-}0.06}^{+0.94}\text{ }\text{ }\mathrm{MeV}$.
