Notes: Abstract Experiments on the reaction:3He+3He→4He+2He using a single four detector telescope have shown evidence for the production of deuteron pulses, consistent with the2He→2H+e++v fusion reaction in the final state. New measurements on the same reaction using improved techniques viz.A) a windowless3He gas target andB) α- d correlation detection with 5 ns resolving time and antipileup circuitry have been performed. Calibrations were obtained from the7Li+3He→2H+4He+4He reaction spectra. The correlation angles were 30° and 97° for the alphas and deuterons respectively. Deuteron pulses have been observed, correlated with alpha particles. A cross section of (1.7 ±0.5)nbsr−1MeV−1 was obtained consistent with previous measurements using a single telescope.

Notes: Near infrared reflectance analysis (NIRA) provides a quick and reliable method for the measurement of end and functional groups in polymers and polymeric products. Feasible applications of Technicon InfraAlyzer for the simultaneous determination of OH and COOH numbers from polyester resins, and percent nitrogen estimation in crosslinkable acrylamido derivatives of partially esterified cellulosic materials were studied. The analytical results obtained show that NIRA techniques provide accurate and precise measurement of functional and end groups from the polymer samples used for this study. In addition, the statistical data showed that the number of samples used in learning sets were adequate for the generation of reliable calibration equations.
