| Research Abstract |
In the present research project following results have been obtained.
(1) Pulse radiolysis study of ・NO_3 radical-formation mechanism, yield and reactivity.
(2) Pulse radiolysis study of ・SO_4^- and ・H_2PO_4^- radicals-formation mechanism, yield and reactivity.
(3) Reduction of G (-Ce^<4+>) in concentric nitric acid.
(4) Quantitative evaluation of direct effect in concentric nitric acid.
(5) Evaluation of water decomposition products as a function of nitrate ion.
(6) Pulse radiolysis study of ・ClO_3 in concentrated chlorate solution.
(7) Pulse radiolysis study of ・ClO_4 in concentrated perchlorate solution.
(8) Construction of a computer code for the calculation of the spur reactions.
(9) Construction and simulation of a new spur diffusion model including ultrafast reactions.
(10) A database for the simulations of radiation induced reactions of nitrogen compounds.
