Abstract
THE effect of gravitational radiation on an elastic body has been previously investigated1. The component varying with time of the Riemann tensor (R iojo) associated with the gravitational field acts as a driving term in the wave equation for the strain or displacement. It was proposed1 that the normal modes of the Earth or a laboratory mass be used as a detector of gravitational radiation. Experiments to measure the interstellar gravitational radiation at kilocycle frequencies are at present in progress at the University of Maryland.
