On the Shape of Cosmic Ray Modulation during Evenand Odd-Numbered Solar Activity Cycles
Abstract
Data from several neutron monitors are used to investigate the cosmic ray modulation for different rigidity intervals in the period 1953-2002. From the shape of the cosmic ray modulation it turns out that the ∼1.3-yr periodicity, identified also by the use of the wavelet technique, results highly significant during the second stage of cosmic ray modulation in even/odd heliomagnetic semicycles.
