通过HgBr（2）的光解，在404.7nm处首次观察到了汞原子7（3）S（1）-6（3）P（0）跃迁的强荧光。当用ArF（193 nm）激光激发HgBr（2）时，只有在一定的温度范围内（130-160 ℃）才能获得超荧光。简要讨论了激发态汞原子的形成机制和低亚稳态6（3）P（0）的猝灭机制。
Strong fluorescence with high directionality was observed for the first time to our knowledge from the mercury atomic transition 7(3)S(1)-6(3)P(0) at 404.7 nm by the photodissociation of HgBr(2). Superfluorescence could be obtained only in a limited temperature region (130-160 degrees C) when HgBr(2) was excited by an ArF (193-nm) laser above a certain threshold power. Mechanisms for the formation of the excited mercury atom and for the quenching of the lower metastable state 6(3)P(0) are briefly discussed.
