Abstract

The polarisation of the fluorescence spectra of the organic scintillation crystals naphthalene, anthracene, terphenyl, quaterphenyl and stilbene is measured by excitation with α-particles. The measurements are carried out with thin crystal plates of different crystallographic orientation and for different angles of incidence of α-particles. Careful experiments showed that the polarisation values of anthracene do not depend on the angle of incidence of α-particles. A simple model is proposed for explaining the results and the polarisation values are discussed and compared with corresponding values of UV-investigations of other authors.
