我们报道了使用直接双质子敲除反应9Be(38Si,36Mg+ γ)X在83 MeV/核子下对非常富中子核（36）（12）Mg24进行的第一次光谱研究。测量了36Mg的第一激发态2+的能量E(2+(1)=660(6) keV。根据蒙特卡洛壳模型计算，基态和2+(1)态的部分截面的大小表明，在最低的状态下存在强入侵者外合物。
We report on the first spectroscopy study of the very neutron-rich nucleus (36)(12)Mg24 using the direct two-proton knockout reaction 9Be(38Si,36Mg+gamma)X at 83 MeV/nucleon. The energy of the first excited 2+ state of 36Mg, E(2+(1)=660(6) keV, was measured. The magnitude of the partial cross sections to the ground state and the 2+(1) state is indicative of strong intruder admixtures in the lowest-lying states as suggested by Monte Carlo shell-model calculations.
