Experimental lifetimes of some levels belonging to the 4p45d configuration of KrII

Lifetime of eight levels belonging to the 4p45d configuration of singly ionized krypton have been measured by high-frequency deflection technique with a delayed coincidence single photon counting arrangement. The results have been compared with other experimental and theoretical values. The lifetimes of the 5d4P1/2, 5d′2D3/2, 5d′2F5/2, 5d2P3/2 and 5d2P1/2 levels have been measured for the first time.
