负碳原子离子和团簇离子被储存在静电离子储存环中。亚稳态原子离子的寿命受周围环境黑体辐射的影响很大。通过在环中引入稀有气体靶，得到了C-原子离子的碰撞诱导脱离截面。对于团簇离子Cn-（n = 2 ~ 8），通常观察到亚毫秒至毫秒寿命的亚稳离子衰变。
Negative carbon atomic ions and cluster ions were stored in an electrostatic ion storage ring. The lifetime of the metastable atomic ion is heavily affected by the blackbody radiation from the surrounding environment. By introducing rare gas target into the ring, collision-induced detachment cross sections of the atomic ion C- were obtained. For cluster ions Cn- (n = 2 ~ 8), decay of metastable ions with sub-millisecond to millisecond lifetime was commonly observed.
