Abstract
THE intensity variations of the cosmic radiation during the solar cycle can be well simulated by assuming a heliocentric decelerating potential that is applied to the particles arriving from interstellar space1,2. During the past few years experimental and theoretical understanding of the process of solar modulation has improved greatly. It now seems that a full treatment of the diffusive-convective motions of the particles in the radially expanding solar wind results in an energy loss by the individual particles which can, on average, be treated as analogous to the effects of a potential, except for particles of quite low energies ≤ 100 MeV, where the analogy fails.
