Flashes of alkali metal atomic lines during multibubble sonoluminescence are 10 ns in duration, while continuum flashes are less than 1 ns long. Using time-correlated photon counting, we have established that both processes occur almost synchronously with a delay in the intensity maxima of atomic line flashes relative to those of continuum flashes. The delay increases in sequence Na (589 nm), Li (670 nm), K (767 nm), Rb (780 nm from 0.1 to 0.8 ns, which correlates with a decrease in the excitation energy of the metal spectral line. The results confirm interrelation between the processes of the continuum and atomic lines emission. Temporal features of the continuum flashes are also discussed. Keywords: multibubble sonoluminescence, alkali metals, flash duration, flash sequence, correlation method.
