Abstract
A 3.5 MeV Dynamitron accelerator has been used to investigate low pressure mixtures of Kr-NF3, Xe-NF3, Kr-NF3-UF6, and Xe-NF3-UF6. The accelerator provides low intensity, guassian shaped, pulsed proton beams with FWHM pulse widths of 3 ns and repetition rates of 1 microsec to 32 ms. Emissions from the gas scintillation cell are observed with a single proton counting system. Under existing experimental conditions, the metastable reaction channel dominates the system kinetics, and analysis of experimental results gives formation rate constants, K(1), of 1.7 x 10 to the -10th power cc/sec and 5.5 x 10 to the -11th power cc/sec for the reactions Kr* + NF3 to KrF* + NF2 and Xe* + NF3 to XeF* + NF2, respectively. The results of absolute conversion efficiency measurements show the Xe-NF3 system to be approximately an order of magnitude more efficient than the Kr-NF3 system. The addition of approximately 0.75 torr of UF6 to a 40/2 torr mixture of Kr/NF3 reduces the 2487 A emission by approximately 50%. A 50% reduction in the 3525 A emission from a 40/4 torr mixture of Xe/NF3 is observed when 2 torr of UF6 are added. ad
