• By making use of miniature <SUP>239</SUP>Pu and <SUP>235</SUP>U fission chambers and an accelerator-based neutron source, the <SUP>239</SUP>Pu/<SUP>235</SUP>U neutron fission rate ratio profile has been measured in the region of a plane interface between a tank containing ordinary water and a tank containing an aqueous solution of boric acid. The reported preliminary results indicate an approximately 8 mm shift of the central point of the fission rate ratio profile towards the poisoned side of the system and an accompanying larger shift in the <SUP>235</SUP>U Cd ratio profile towards the unpoisoned side.
