Multiple scattering effects due to a random array of obstacles are considered. Employing a ``configurational averaging'' procedure, a criterion is obtained for the validity of approximate integral equations describing the various field quantities of

Measurements of changes in ultrasonic attenuation together with changes in ultrasonic velocity have been made concurrently with load strain measurements in tensile tests on the same specimen of aluminum. The results of such measurements taken during

An rf ion source has been constructed, which yields up to 15 ma of hydrogen ion current consisting of 80–90 percent protons. The ion current yield has been studied as a function of rf power and frequency, gas pressure, and dc (extracting) voltage.

A study is made of the ultrasonic field produced by a circular quartz crystal transducer and the integrated response of a quartz crystal receiver with the same dimensions as the transducer. The transducer and receiver are taken to be coaxial, and it

The measurement of ultrasonic attenuation and velocity at megacycle frequencies demands that the sample faces be parallel within limits that require extreme care. The importance of maintaining the tolerances in question is shown in terms of the echo

A brief review is given of the calculation of cross section expressions for the scattering of an elastic wave in an elastic medium. With scatterers that are elastic and spherical in shape, numerical calculations are carried out for non‐Rayleigh con
