A scintillator, based on the direct effect of a radiation upon a dissolved activator, has been suggested. Concentrated /2–2.5 mol/1/ solutions of Tb3+ in D2O and H2O, and aqueous solutions of HCl, HNO3, and HClO4 have been found to possess a high light output of scintillations affected by -particles of actionoids. The scintillation efficiency of terbium solution in D2O is higher than that of some well-known organic scintillators. The terbium scintillator is quenched feebly by actinoid salts. Besides, it is of low sensitivity for the - and -radiation. The scintillations in terbium solutions represent groups of separate single-electron pulses with an exponentially decreasing frequency of their occurrence within groups.

Thermal dissociation processes of compounds with the composition MoO2(C6H5CONHO)2.nA (A-polar organic solvent: alcohols, aldehydes, ketones, organic acids) were investigated. Kinetics of dissociation was studied in a flow reactor, the values of activation energy and preexponential factor were calculated. The influence of a solvent nature, of the length of included molecules and of the type of crystalline lattice was studied. The sequence of kinetic stability was obtained. It corresponds to the sequence of solvent activity with respect to H-binding up with the complex. For the series of alcohols nonmonotonous dependence of kinetic parameters on the length of chain (with the division into two groups: with even and oddn) was obtained. For all the compounds studied a compensation relationship is observed (lgA=aE+b).
