Translated from Astron. Zh.; 49: No. 6, 1229-1237(1972). Peebles and Dicke's hypothesis for the cosmological origin of globular clusters is applied to consider the possible fragmentation of primordial clouds into stars by thermal instability for a wide range of initial conditions. Thermal instability would cause the central part of a cloud to disintegrate; it would cease to contract because of the passage of weak shock waves heating the material to 2000 to 5000 deg K. If the central cloud temperature is lower, a star with M approximately 10/sup 2/ M/sub sub solar / will be generated. Globular protoclusters will become isolated from the background Friedmann expansion when z > 10, and the most probable epoch for such events would be z approximately 40. (auth)
