摘要：
We have analysed the relationship between cosmic rays and coronal index of solar activity (CI) for the periods of negative (A < 0), Mix and Positive (A > 0) polarities of the general magnetic field of sun. In cosmic ray modulation sunspot numbers are being generally used as a reliable solar parameter. In this analysis, we have used coronal index as a new solar parameter for long-term cosmic ray modulation. Negative and high correlations are found between CI and cosmic rays for the A > 0 epochs and A < 0 epochs of solar magnetic field. However, significant differences are found between A > 0 and A < 0 epochs. Correlations are found poor during the mix polarity years.
