Die Szintillationslichtausbeute energiereicher Deuteronen und α-Teilchen in organischen Kristallen

The light output of anthracene and terphenyl bombarded with deuterons from 8 to 25.3 MeV and with α-particles from 20 to 49.5 MeV has been measured as a function of energy. Both anthracene and terphenyl gave for low energies a nonlinear response tending towards linearity above 18 MeV for deuterons and 35 MeV for α-particles. The dependence of the light output upon the impact direction of the incident particles has been found not to be disappearing even at highest energies, but in contrast there appear new fine structures. Furtheron the specific light outputdS/dxvs specific energy lossdE/dx has been investigated in direct measurements on thin crystals. The quantitydS/dx depends on the impact direction even atdE/dx=35 keV/mg cm^?2.

Über spektroskopische Untersuchungen mit Hilfe von α-Teilchen

Excitation of the molecules of various gaseous substances byα-particles from a polonium 210 source has been investigated, expecially with respect to the branching between dissociation andγ-de-exitation. The use of an alternative irradiation source is briefly discussed.
