Strongly amplified spontaneous emission (ASE) has been observed on the 366.5 nm UV broad-band transition in molecular sodium. Pump energy and Na2-density dependences indicate clear thresholds for this emission in comparison with the well-known violet bands of Naz. Simple gain calculations, based on
