An artifical auroral experiment, Precede, was performed in the 80- to 120-km altitude range above the White Sands Missile Range, New Mexico, in October 1974. A 2-kW rocket-borne electron accelerator, square wave modulated at 0.5 Hz, was activated at 95 km on payload ascent, was pulsed continuously through apogee (120 km) to a descent altitude of approximately 80 km, and provided a total of 90 pulses of a 2.5-kV 0.8-A electron beam over a period of 180 s. A ground-based dual channel telephotometer recorded the time-dependent photon emission rate of the N2' (B2&Sgr;u'→X2&Sgr;x') first negative (0--0) band at 3914 ¿ and the O(1S→1D) transition at 5577 ¿ induced in the night atmosphere by the pulsed electron source. An electron-induced luminous efficiency of (4.5¿0.4) ¿103 was determined for the N2+ IN(0--0) transition at 3914 ¿ in the 80- to 100-km altitude range. The photon emission rates of several bright stars were measured to calibrate the telephotometer and to correct or the efects of atmospheric extinction. The time-dependent O(1S) 5577-¿ photon emission rate has been fitted with a model calculation providing insight into O(1S) production and loss processes resulting from the deposition of energetic electrons in the 90- to 116-km altitude range. At altitudes in excess of approximately 110 km the O(1S) time-dependent photon emission profiles indicate that consecutive reactions involving energy transfer from N2(A3&Sgr;u1) to O(3P) is the dominant O(1S) production process. A rate coefficient of 5.7¿10-12 cm3s-1 representing an O(1S) yield of 0.29 has been inferred from the data for the reaction of N2(A3&Sgr;u+) and O(3P). The dissociative recombination of O2+ has been established as the dominant O(1S) production process at altitudes less than 96 km with an O(1S) yield of 4.5--6.0% per dissociation.Other processes account for approximately 20% or less of the total O(1S) production at 90 km with smaller contributions indicated at higher altitudes. Collisional deactivation by O(3P) accounts for approximately 50% of the total O(1S) depopulation rate in the 95- to 116-km altitude range with a rate coefficient of 6.010-11e305&tgr; cm3 s-1. Quenching by O2 dominates as an O(1S) loss mechanism at altitudes less than 94 km with an estimated rate coefficient of 1.2¿10-11e-850&tgr; cm3 s-1. The rate coefficients determined for O(1S) produced by the reaction of N2(A3Ju+) and O and the collisional deactivation processes have a probable error of approximately 25% if it is assumed that the model atmosphere used in the analysis contributes no significant uncertainty.
