Quantum Raman spectroscopy. II. Isotope ratio measurements in oxygen and nitrogen
Measurements of the /sup 14/N/sup 15/N//sup 14/N/sup 14/N and /sup 16/O/sup 18/O//sup 16/O/sup 16/O Raman intensity ratios have been made in air samples and pure gas samples. A high-resolution double monochromator was used with a C31034A-02 PM tube to count the photons scattered from a low-powered laser beam (1--2 watts). Standard high-speed modular electronics (approximately 10 ns resolution) were used to process the output pulses. The ..delta..J = 0 vibrational bands of /sup 14/N/sup 15/N and /sup 16/O/sup 18/O were observed to be essentially free of all interference except dark noise of approximately 3 counts/sec. The adjacent rotational structure of /sup 14/N/sup 14/N and /sup 16/O/sup 16/O showed no appreciable overlap with the ..delta..J = 0 bands of interest. Detailed spectra, comparison of the Raman intensity ratios with mass spectrometer isotope ratios, and Raman cross section data for /sup 14/N/sup 15/N and /sup 16/O/sup 18/O are presented. The applicability of Raman scattering as a technique for precision measurement of isotope ratios is discussed.

DT fusion neutron radiation strengthening of copper and niobium
The initial results of a comparative study of the radiation strengthening and damage structures produced in Cu and Nb by D-T fusion and fission reactor neutrons are described. The radiation strengthening produced by a given fluence of fusion neutrons above about 10$sup 17$n/cm$sup 2$ is equal to that produced by a fluence of fission reactor neutrons (E greater than 0.1 MeV) ten times as great. This difference is about twice as large as would be expected if the strengthening scaled with damage energy or dpa. Initial transmission electron microscopy observations of the damage structures in fusion and fission reactor neutron irradiated copper indicate that the same type of primary structural defects, vacancy and interstitial point defect clusters and small dislocation loops with a/3 (111) and a/2 (110) Burgers vectors, are produced in both cases. The difference in the radiation strengthening produced by fusion and fission reactor neutrons in Cu appears to result from a substantially greater rate of accumulation of damage, in the form of point defect clusters, during irradiation with fusion neutrons than during irradiation with fission reactor neutrons plus a significant difference in the size and spatial distributions of the damage clusters.
