The propagation of the transverse-longitudinal acoustic pulses through astrained cubic crystal containing the resonant paramagnetic impurities witheffective spin S=1 is investigated. It is supposed that the pulses propagateunder arbitrary angle with respect to the direction of the external staticdeformation parallel to the fourth-order symmetry axis. In this geometry, boththe transverse and longitudinal components of the acoustic field have thehigh-frequency and zero-frequency spectral components. We show that a pulse canpropagate in the modes different from the acoustic self-induced transparency.In particular, a pulse propagating in the mode of acoustic self-inducedsupertransparency substantially changes the populations of the spin sublevels,but its group velocity remains almost equal to the linear velocity of thesound. If a pulse propagates in the acoustic extraordinary transparency mode,then its group velocity is substantially lower while the sublevel populationsremain virtually invariant. Also, the modes of propagation under conditions ofweakly excited spin transitions and large detuning of the pulse high-frequencycomponents are identified.Comment: 10 pages, 3 figures, RevTeX, minor change
