Abstract

We present the results of a detailed, quantitative study of the solar modulation of cosmic-ray protons and He nuclei. The study is based on: (a) observations over the 1966 to 1970 period with balloon- and satellite-borne instruments, (b) numerical solutions of the cosmic-ray transport equation, and (c) propagation parameters derived from studies of near-Earth and interstellar spectra of cosmic-ray electrons. We find that consistent, quantitatively satisfactory results may be obtained with a model of solar modulation which uses a diffusion coefficient separable into functions of heliocentric radius and particle rigidity and in which adiabatic deceleration has a dominant role in shaping the low-energy spectra of nuclei near 1 AU.
