It was shown in previous papers that trapped charge carriers can be used at low temperatures for detection and free path determination of single phonons. Using this method it is shown now that because of the high phonon density of a phonon pulse generated by one alpha-particle the action of such phonons on trapped charge carriers is mostly a multiphonon action so that the carriers can be released from trap depths which are much greater than the energy of a single phonon. Because of the great
