Photonuclear reactions in the targets /sup 2/7Al, /sup 2/8Si, /sup 3/1P, /sup 3/2S, and /sup 4/0Ca have been studied for maximum bremsstrahlung energies of 2, 2.4, 3, and 4.5 GeV. The yields of the residual nuclei /sup 7/Be, /sup 1/1C, /sup 1/3N, /sup 1/8F, /sup 2/2Na, and /sup 2/4Na were measured by means of a germanium-lithium semiconductor detector with a sensitive volume of 30 cm/sup 3/. In discussion of the results we took into account the contribution of the low energy part of the bremsstrahlung spectrum. Comparison of the measured yields with estimates calculated by Rudstam's formula permitted us to conclude that there is a difference in the mechanism of formation of the light fragments /sup 7/Be, /sup 1/1C, and /sup 1/3N from that of the other residual nuclei /sup 1/8F, /sup 2/2Na, and /sup 2/4Na.
