摘要:
The phase of the dynamic polarization echo with respect to the second driving pulse has been measured for several powdered materials. The mechanism for echo formation, in all the materials that were examined, was found to be an anharmonic oscillator interaction with a nonlinear amplitude‐dependent frequency.
