To study the kinetics of surfactant systems below, at, and above the critical micelle concentration cmc, broad-band ultrasonic spectra of short-chain ionic surfactant solutions are evaluated. Within the measurement frequency range from 100 kHz to 4.6 GHz the spectra reveal a relaxation term that, at...
