摘要

Low-energy spectra of the ^8,10He nuclei were investigated in the (t, p) -type reactions at small centre-of-mass angles using ̃ 25 AMeV beams of ⁶He and ⁸He nuclei. The 0⁺ ground state (g. s.) of ⁸He and excited states, 2⁺ at 3. 6-3. 9MeV and (1⁺) at 5. 3-5. 5MeV, were populated with cross-sections of 200, 100-250, and 90-125μb/sr, respectively. To account for a near-threshold anomaly observed in the ⁸He spectrum the population of a 1^- continuum (soft dipole excitation) was considered. The lowest-energy group of events in the ¹⁰He spectrum was observed at ̃ 3 MeV with a cross-section of ̃ 140 μb/sr. This result is consistent with the previously reported observation of ¹⁰He providing a new g. s. position for ¹⁰He at about 3MeV.
