ABSTRACT: The transfer reaction p(8He, d)7He with the exotic 8He-beam has been studied by correlational measurements, and an excited state of 7He was observed. Most likely, it has a structure with a neutron in an excited state coupled to the 6He-core which itself is in the excited 2+-state. The transfer reaction p(8He, 2He)7H was also studied, and manifestation on the possible existence of the resonance 7H was obtained.

ABSTRACT: (i) The excited state of 11Li at E∗ ∼ 1.3 MeV observed in the proton inelastic scattering was recently reinterpreted in terms of shakeoff mechanism with proton scattering on the 9Li-core. However, the observed peak has constant excitation energy along its kinematical locus. This fact represents the most important criterion of excited state. This constant energy contradicts to the shakeoff mechanism. (ii) Preliminary results of recent spectroscopic studies of 7He and 7H are reported. The excited state of 7He was observed (E∗ = 2.9±0.3 MeV, Γ = 2.2±0.3 MeV, Γα/Γtot = 0.85±0.15). This state has unexpected structure resulting in decay into the channel α+3n, but not into 6He+n. Hint on a possible existence of resonance 7H was obtained. © 1998 American Institute of Physics.
