Characteristics of the proton and alpha solar wind components after the passing of interplanetary shock waves by observations on the ''Prognoz'' satellite in May, 15 and 30, 1972

The ''Prognoz'' high-apogee satellite was used to conduct a separate measurement of proton and α-components of the solar wind by means of an energy-mass analyzer. During the period of high activity in the interplanetary space on May 15 and 30, 1972 essential differences in the behavior of components were established: the distribution functions over velocities were close to maximum for α-particles and differed from them considerably for protons. After the passing of shock waves the increase of the proton temperature was greater than that of the temperature of α-particles, then the temperature ratio returned to a quantity which was typical for the solar wind. On May, 15 a substantial increase of proton velocity occurred as compared with the velocity of α-particles. On May, 30 the two-stream structure of proton component was observed
