A new class of scintillators for neutron imaging, based upon lithium gadoli
nium berate, is described. These scintillators offer the ability to tailor
their response to the neutron spectrum by varying the relative absorption o
f neutrons by the key constituents (lithium, gadolinium and boron). The iso
topic compositions of each constituent can be varied in order to change the
spectral response. (C) 1999 Published by Elsevier Science B.V. All rights
