Abstract
We have developed an interesting and widely applicable technique for m easuring lifetimes of low-lying levels of neutral atoms and their firs t few ionization states. The cascade-photon-coincidence method has bee n extended by using a light source consisting of excited atoms sputter ed from a solid by 10-keV have measured the lifetimes of the 4p(2)P(3/ 2)(o) state of Ca II, the 6p P-2(3/2)o state of Ba II, and the 4p(2)P( 3/2)(o) state of Al III. These measurements are in good agreement with earlier work.
