THE SCINTILLATION ANISOTROPY OF ANTHRACENE AT LOW TEMPERATURES. PART II
The scintillation anisotropy of anthracene bombarded with alpha particles was measured as a function of temperature between 1.9 and about 80 deg K. With all crystal specimens investigated, a pronounced minimum was found between 20 and 30 deg K. The anisotropy is constant below about 9 deg K, whereas the light yield still increases with decreasing temperature down to 1.9 deg K. The light yield was found to be a nonlinear function of the temperature, (auth)
