Abstract Single crystals of anthracene andp-terphenyl have been bombarded with α-particles. The angle of incidence with respect to the crystal axes was varied. The directional intensity of the scintillation light was investigated as function of the decay time of the scintillator. During the first 100 nsec after the excitation of the crystal the anisotropy of the scintillation light yield decreases starting with a value larger than that measured with pulses of 1000 nsec length. For the next 900 nsec the anisotropy remains nearly constant being still higher than 1. Therefore the anisotropy of the fast component of the scintillation light is larger than the anisotropy of the slow component. The results are discussed with reference toBirk's formula.
