Popis:	AIE~+-XIE~ emission 1 in Na2 is observed following excitation ofB n, by various lines of an argon ion laser. The excitation energy of Bin, is collisionally transferred to the (2)~ " which then radiatively populates the AXY~ + state. The Na vapour is contained in a stainless steel crossed heat pipe with Ar buffer gas and temperature around 600°C. For all laser lines except 4579A, the coarse features of A-X emission are independent of the laser wavelength. However, at high resolution the finer differences between different laser line excitation are explained. Various v'-v" transitions in this emission are identified. Computer simulation is presented to help explain some features of this emission.
