We have obtained the population of n=17, m=0 Stark states of sodium atom in the static electric fields ranged from 1250 to 2000 V/cm by two step excitation with tunable lasers. The lifetimes of the Stark manifold states are measured by using delayed electric field ionization. The influences of applied fields and blackbody radiation on the determination of the lifetimes are discussed.
