The use of Nd and Pr deuterides and tritides for hightemperature hydrogen isotope targets was investigated, and the results were compared with those on Zr or Ti films. Results of dissociation pressure as a function of composition for the Nd-H system showed that for atomic ratios of hydrogen to metal up to 1.9: 1, NdH is thermally much more stable than TiH. Plots of log dissociation pressure versus the reciprocal of temperature for NdH/sub 1.9/, PrH/ sub 1.9/, TiD/sub 1.5/ , and ZrD/sub 1.45/ show that at 500 deg C the dissociation pressure of NdH/sub 1.9/ is about 6 orders of magnitude less than that of TiD/sub 1.5/ and about 4 orders of magnitude less than that of ZrD/sub 1.45/. The results indicate that a target of composition NdH/sub 1.9/ should withstand temperatures at least 200 deg C higher than the target based on Ti or Zr. (P.C.H.)
