Abstract
[Problems to be Solved] A colquiriite-type crystal preferred for a scintillator for neutron detection, which has high sensitivity to neutron and which is reduced in background noise attributed to γ rays; a scintillator for neutron detection which comprises this crystal; and a neutron detector are provided. [Means to Solve the Problems] A colquiriite-type crystal represented by the chemical formula LiMMX, such as LiCaAlF, containing Na and Ce, for example, the colquiriite-type crystal containing at least one alkali metal element selected from the group consisting of Na, K, Rb and Cs, and a lanthanoid element selected from the group consisting of Ce, Pr and Nd, and having an isotopic ratio ofLi of 20 mol % or more, preferably 50 mol % or more; a scintillator for neutron detection comprising the colquiriite-type crystal; and a neutron detector.
