Abstract

A new scintillator material for the detection of fast neutrons that consists of a methanol adduct of cerium trichloride with the composition CeCl₃(CH₃OH)₄ has been characterized using 14.1 MeV neutrons from a deuterium-tritium neutron generator and fast neutrons from a bare instrumented ²⁵²Cf source. The timing resolution of the scintillator for fast neutrons was found to be ̃ 1 ns. Neutron interactions in the CeCl₃(CH₃OH)₄ composition were simulated using the MCNP-PoliMi code. These simulations indicate that proton recoils account for most of the deposited energy in CeCl₃(CH ₃OH)₄. The crystalline molecular adduct CeCl ₃(CH₃OH)₄ represents a rare-earth metal-organic scintillator that can be applied to both fast neutron and gamma-ray detection.
