Measurements of the energy spectra of delayed neutrons for the isotope-separated, fission product precursors /sup 93 -97/Rb and /sup 143 -145/Cs, over the energy region from about 10 to about 1300 keV are reported. These data were obtained at the TRISTAN ISOL facility using gas-filled proton-recoil pro portional counters. The data for each of the rubidium and cesium isotopes show good qualitative agreement with the existing /sup 3/He ionization chamber data at energies above about200 keV. In addition, they provide definitive spectral information down to about10 keV. Of particular note is the observation of line structure below about 200 keV with energy resolution much better than that obtained using /sup 3/He ionization chambers.
