Experimental Evidence for the Existence of 7H and for a Specific Structure of 8He
Abstract
Experimental search for the superheavy
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.
