Abstract
The lifetime of the metastable autodetaching 4PI(g) state of the He2- ion has been measured by a time-of-flight technique to be 135 +/- 15 m us, using a heavy-ion storage ring, The lifetime is nearly a factor of three shorter than the only available theoretical prediction. It is p roposed that the lifetime should be assigned to the 4PI(g)- LAMBDA dou bling component.
