摘要

The low-lying spectra of ⁸He and ¹⁰He nuclei were studied in the ³H(⁶He, p)⁸He and ³H(⁸He, p)¹⁰He transfer reactions. The 0⁺ ground state (g.s.) of ⁸He and excited states, 2⁺ at 3.6 - 3.9 MeV and (1⁺) at 5.3 - 5.5 MeV, were populated with cross sections of 200, 100-250, and 90-125 μb/sr, respectively. Some evidence for a ⁸He state at about 7.5 MeV was obtained. We discuss a possible nature of the near-threshold anomaly above 2.14 MeV in ⁸He and relate it to the population of a 1^- continuum (soft dipole excitation) with a peak value at about 3 MeV. The lowest energy group of events in the ¹⁰He spectrum was observed at ∼3 MeV with a cross section of ∼ 140 μb / sr. We argue that this result is consistent with the previously reported observation of ¹⁰He providing the new ¹⁰He g.s. position at about 3 MeV.
