    The Large Observatory for X-ray Timing (LOFT)

    High-time-resolution X-ray observations of compact objects provide direct access to strong-field gravity, to the equation of state of ultradense matter and to black hole masses and spins. A 10 m2-class instrument...

    Phonon-Defect Interaction

    In this chapter we wish to discuss the interaction of phonons with defects. We will only consider the effect of this interaction on the phonons themselves. The study of the properties of defects in crystals is...

    Study of the Resonant Phonon Scattering in KCl:Li Using the Spin-Phonon Interaction

    The recent interest in defect modes has been fueled in large measure by their effect on the low temperature thermal conductivity of the host crystal. Beginning with the work of Walker and Pohl,(1) the change in t...
