DIRECTIONAL ANISOTROPY IN THE CHARACTERISTICS OF THE ORGANIC-CRYSTAL SCINTILLATORS
The directional anisotropies in the scintillation responses of anthracerie and trans-stilbene scintillators to fast neutrons are measured by changing the direction of the incident neutrons to the scintillators. For anthracene, the directions of the neutrons that correspond to the maximum and minimum scintillation yields coincide with the c'- and b-axes, respectively, where the c' axis is defined as the axis perpendicular to the ab plane. The directional anisotropy of the fast decay component is much more significant than that of the slow decay component. For trans-stilbene, no definite correlation is established between the anisotopies in the scintillation responses and the crystal structure because of the complexity of the crystal used. (auth)
