Book Description
In experiments to determine if there is any change in the fraction of recoil-free emissions of gamma radiation from Fe/sup 57/ due to pressure increases, no measurable changes were found at pressures up to 40,000 psi. Experi-mental apparatus is being developed to measure the acoustical power of transducers in the megacycle frequency range using nuclear resonance techniques. (J.R.D.).

Book Description
The effect of polarizing mngnetic field intensity on the nuclear resonant absorption was studied by varying the field strength at a 1-mc Co/sup 57/ source from 0 to 1000 gauss while keeping the absorber between the poles of a magnet having a fixed field of 800 gauss. The rates of resonance absorption change with field intensity were greatest in the region of 300 to 1000 gauss, and the% nuclear resonant absorption for 1000-gauss fields was 8.5 and 26% for perpendicular and parallel fields, respectively, as compared with 15% for no fields. Other absorption measurements for Co/sup 57/ sources are also reported. Calculations on the use of nuclear resonant absorption to measure gravitational fields and altitudes were made which indicates that this application is not promising. (D.L.C.).
