Lasing action was achieved on the B2Σ+X2Σ+ transition of HgBr by dissociating HgBr2 vapor by electron collision in a transverse electric discharge. The lasing wavelengths, consisting of six lines between 502 and 505 nm, are identical with the ones previously measured by excitation through photodissociation.
