THE DIRECTION DEPENDENCE OF THE SCINTILLATION LIGHT YIELD OF THIN ANTHRACENE AND STILBENE CRYSTALS IN COLLISIONS WITH /cap alpha/ PARTICLES (in German)
The scintillation light yield of thin anthracene and stilbene crystals bombarded with alpha particles of ThB is investigated. A strong dependence of the light yield on the direction of incidence with respect to the crystal axes is found, confirming the results of previous measurements with thick anthracene crystals. For anthracene, maximum light yield occurs for alpha particles incident approximately parallel to the c' axis. With stilbene crystals a minimum of the light output is found in the c' direction. Furthermore, for thin anthracene crystals the direction of maximum light output depends slightly on the crystal thickness. (auth)
