Small-Charge Explosions in Air at High Altitudes,

Abstract

Observations of the luminosity created by 13.5 gram pentolite spheres have been made--primarily in air but also in O2 and N2-- at simulated altitudes of burst from sea level to 100 Kft. The luminosity behavior of these small charges with changes in altitude suggests that the luminosity is primarily created by interactions of the explosion products with the outside atmosphere. No new spectral line or band species are observed, but a broad band of emission does arise with increasing altitude. A second pulse of light is also observed at high altitudes. This second pulse is seen at late times and appears to originate from the core region of the fireball. (Author)
