Success of Oct. 8, 1969, experiments to test validity of Einstein theory of relativity with radiotelescopes for first time was reported to press by team of Cal Tech astronomers. Einstein equations inferred that light, radio, and other electromagnetic waves were deflected by sun's gravitational field at rate of 1.7 secs of arc. Cal Tech team, using 64-m-dia (210-ft-dia) dish-shaped radio antennas at two observatories near Los Angeles, had obtained figures of 1.82 and 1.77 secs, which astronomers credited with accuracy within 10%. Previous optical measurements had contained only 20% accuracy. (AP, W Post, 6/15/70, A8)
