Heliospheric modulation of cosmic rays: model and observation

“…This suggests that in SA cycle 23 the mirror mechanism played a key role in the formation of CR intensity decreases. To be effective, the mechanism also requires the presence of a sufficiently laminar magnetic field in the interplanetary space [Krymsky et al, 2009]. Furthermore, the authors have also established that entire cycle 23 as compared to previous ones is characterized by a reduced level of SW turbulence in the energetic region of frequency spectrum.…”

Investigations of short-term variations of vector and tensor anisotropies of cosmic rays using magnetic mirror model

“…A regular magnetic field influences on CR with such way that a part of particle trajectories are forbidden. The case when the forbiddance is caused by a magnetic mirror was considered in [3]. Wherein it was supposed that the scatterings of particles in the field do not take place.…”
