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.
