✦ Synopsis

Angular structures in the far-field scattering from bubbles are observed and modeled. Mie theory supports a model of diffraction and interference near the critical scattering angle. A new expression for the angular spacing of fine structure is derived. Photographs of scattefing show some of the predicted features. Application of these structures to bubble sizing and detection are summarized and the theoretical extinction coefficient in water is plotted.

Mie computations for bubbles in water also reveal backward and forward glory effects. These are partially manifested as cross-polarized seattering. Observed scattering from bubbles in the near backward direction is found to have a strong cross-polarized component.

The generalized transport equations derived in 1 for the coupled electron-phonon system are solved in the collision-dominated regime. The solution is obtained without making any relaxationtime-approximation. The sound velocity and the ultrasonic attenuation are calculated with the help of the equat
