利用动量分辨的电子-离子多重符合方法，我们明确地确定了NeAr从内价双空位态Ne-Ar（2+）（3s（-2））到外价三空位态Ne（+）（2 p（-1））-Ar（2+）（3 p（-2））的原子间库仑衰变。这是第一次观察到三个电子（3e）参与的原子间库仑衰变。结果表明，这种3e原子间库仑衰变明显快于其他竞争过程，如荧光衰变和通过曲线交叉的电荷转移。
We have unambiguously identified interatomic Coulombic decay in NeAr from the inner-valence double-vacancy state Ne-Ar(2+)(3s(-2)) to outer-valence triple-vacancy states Ne(+)(2p(-1))-Ar(2+)(3p(-2)) by momentum-resolved electron-ion multicoincidence. This is the first observation of interatomic Coulombic decay where three electrons (3e) participate. The results suggest that this 3e interatomic Coulombic decay is significantly faster than other competing processes like fluorescence decay and charge transfer via curve crossing.
