Abstract: | We have observed atomic Na and molecular Na2 emissions in the violet region when Na vapor in a heatpipe (~103—1016 atoms/cm3) is irradiated with a pulsed dye laser with output wavelength in the 570–597 nm region. The Na atomic emissions probably result from recombination of Na+ + e- and energy-pooling involving highly excited atoms and molecules, while the diffuse violet emission bands are probably produced through collisions among excited Na atoms and Na2 molecules. |
