Cosmic Ray Scintillations in Random Magnetic Fields with Non-Zero Helicity
Abstract
The cosmic ray scintillation theory is modified for the case of non diagonal IMF correlation tensor. We introduce the term ‘helicity of cosmic ray scintillation’. It describes rotation of the cosmic ray distribution function. It is shown that the helicity of the cosmic ray scintillations and the IMF helicity are alike in nonresonant frequency band. The behaviour of the cosmic ray distribution function in resonant frequency band is considered. The algorithm for two-canal spectral analysis based on an autoregressional method is developed. Empirical functions of helicity of the cosmic ray scintillation and of IMF helicity are obtained for the same time intervals. Observational results are found to be in a good agreement with the theory.
