    • Abstract


      A1Σu+-X1Σg+ emission in Na2 is observed following excitation ofB1πu by various lines of an argon ion laser. The excitation energy ofB1πu is collisionally transferred to the (2)1Σg+ which then radiatively populates theA1Σu+ 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 4579 Å, the coarse features ofA-X emission are independent of the laser wavelength. However, at high resolution the finer differences between different laser line excitation are explained. Variousv′-v″ transitions in this emission are identified. Computer simulation is presented to help explain some features of this emission.
