CsI clusters (Cs{sub n}I{sup {minus}}{sub n+1} n = 0 to 4) in the keV energy range (15 to 45 keV) have been used to bombard CsI targets in time-of-flight mass spectrometry experiments to study the relationships between secondary ion and photon emissions. Single ions and photons were detected simultaneously from the impact of single projectiles. The secondary ion yields from the polyatomic projectiles are proportional to the projectile momentum. The photon yields are roughly proportional to both the electronic and the nuclear stopping powers. The photon emission from the bulk of the CsI targets is attributed to excitonic processes.
