Abstract
In the original language
The H-7 system was populated in the H-2(He-8, He-3) H-7 reaction with a 26 AMeV He-8 beam. The H-7 missing mass energy spectrum, the H-3 energy and angular distributions in the H-7 decay frame were reconstructed. The H-7 missing mass spectrum shows a peak, which can be interpreted either as unresolved 5/2(+) and 3/2(+) doublet or one of these states at 6.5(5) MeV. The data also provide indications of the 1/2(+) ground state of H-7 located at 1.8(5) MeV with quite a low population cross section of similar to 25 mu b/sr within angular range theta(c.m) similar or equal to (17 degrees-27 degrees).
