THE COSMIC RAY SPECTRAL MODULATION ABOVE 2 GV DURING THE DESCENDING PHASE OF SOLAR CYCLE No.19 II:A study of large Forbush decreases

摘要

This is the second of a series of three papers meant to study both the short- and long-term spectral modulation of primary cosmic rays above 2 GV during the time span from the IGY to the IQSY, through a large part of solar cycle no. 19.
