A compilation of thermal neutron capture gamma ray spectra of naturally occurring elements, in both the low amd the high energy spectral regions, using NaI(Tl) scintillation crystals as detectors is presented. Such a compilation of spectra aids in the evaluation of possible practical applications of neutron capture gamma ray techniques. An external beam from the ARF research reactor is used as a source of thermal neutrons for the measurements. During the period covered, low energy capture gamma ray spectra of silicon, sulfur, chlorine, potassium, iron, strontium, and cesium were obtained using the 11/2 in. x 1 in. NaI(Tl) detector and of hydrogen, silicon, chlorine, and osmium with the 3 in. x 3 in. NaI(Tl) crystal. In addition, high energy capture gamma ray spectra of silicon, chlorine, chromium, arsenic, selenium, gadolinium, hafnium, rhenium, osmium, iridium, platinum, and thallium were obtained using the 3 in. x 3 in. NaI(Tl) scintillation detector. (auth)
