Abstract The mean life of the Sp 2P312 resonance level in Ag I has been measured t two different vapor densities using electronic excitation and a method of delayed coincidence. The lifetime values, obtained by optically detecting the decay of the 5p 2F312 5s 251/2 (3280.68 A) resonance transition, increase with increasing vapor density. This vapor density dependence was interpreted as being due to the imprisonment of the 3281 A resonance radiation. The Holstein theory of the imprisonment of resonance radiation was applied to the lifetime-versusvapor density data to yield the following results: TO = 6.5 + 0.6 ns, A3281 = 1.53 + 0.14 x 108 1, and = 0.50 + 0.05. The error limits were derived primarily from estimated uncertainties in the measured mean lives and possible variations in the vapor densities during the runs. Experimental results of other workers are presented for comparison with the results of the present work.
