摘要

利用 ACCULINNA-2 碎片分离器（日本核研究开发机构 FLNR）输出的 29 A⋅MeV 6He 光束，以反运动学方式进行了 6He(d,p)7He 反应，对 7He 核进行了研究。对来自 7He→n+6He 衰变的中子的登记使我们有可能得出 7He 基态参数，即 0.38(2)MeV 的衰变能量和 0.11(3)MeV 的衰变宽度。

Properties of the 7He ground state studied by the 6He(d,p)7He reaction

The ⁷He nucleus was studied using the ⁶He ${(d, p)}^{7}$ He reaction in inverse kinematics at 29 $A \cdot$ MeV ⁶He beam delivered by the ACCULINNA-2 fragment separator (FLNR, JINR). The registration of neutrons from $^{7} He \to n +^{6} He$ decay made it possible to derive the ⁷He ground state parameters, the decay energy of 0.38(2)MeV and width of 0.11(3)MeV.
