7H isotope was performed in the reaction p(
8He,pp)
7H with the
8He beam at 61.3A MeV. The evidence for existence of the
7H state near the t+4n threshold was obtained. In the same experiment, the p(
8He,t) reaction populating the ground and excited 2+ state of
6He was investigated. The obtained results argue on a specific structure of the
8He ground state containing the
6He subsystem in the excited 2+ state with a large weight.
