An electronic method for improving the delayed coincidence method in the measurement of the lifetime of the. excited state of an atom is proposed. A gate circuit which used tunnel diodes was studied. For the tunnel diode 1 N 3219 the calculation led to a rise time of the order of 0.8 nsec. (tr-auth)

The measurement of the absorption of a parallel light beam from a resonance lamp by an absorption tube filled with mercury vapor leads to the determination ot the lifetime of the 6/sup 3/P/sub 1/ excited state of mercury. The same value ( lambda = 1.16 x 10/sup -7/ sec) was found for all the isoiopes of mercury. (tr-auth)
