Radiative Lifetime Measurements of N2(C3IIu), NH(A3II) and NH(C1II)

Abstract

The radiative lifetimes of N2(C3IIu), NH(A3II), and NH(C1II) states were measured by the use of the time-sampling technique. The excited molecules were produced by the electron bombardment of N2 and NH3 gas. The lifetimes obtained in this experiment for N2(C3πII), NH(A3II), and NH(C1II) were (4.8±0.3)×10−8 sec, (4.1±0.2)×10−7 sec, and (4.3±0.2)×10−7 sec respectively. The oscillator strengths of the respective transitions were also calculated.

“…Sawada and Kamada [559] measured T by the time sampling technique. Excitation was by electrons with energies below 200 eVe Time resolution was about 10-8 S. Lifetime was found to be independent of pressure in the range of 1-5X10-3 torr (0.1-0.6 Pa).…”
