Experimental lifetimes of some levels of KrI

Lifetime of nine levels belonging to the 4p5np[n=6,7] and 4p5ns[n=7-9] configuration of neutral 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 9s[3/2]1 and 7p[1/2]0 levels have been measured for the first time.
