THE COSMIC-RAY SPECTRAL MODULATION ABOVE 2GV DURING THE DESCENDING PHASE OF SOLAR CYCLE No. 19 V:The influence on the coupling func¬tions of the nucleonic component

摘要

In this Part V of this series of papers the coupling functions of the nucleonic component of cosmic rays at sea-level and at 1900 m.a.s.l. are computed for different modulation levels in solar cycle No.19. The coupling functions are given for the first time with a high degree of accuracy because of the good knowledge of the sea-level latitude effect of the nucleonic component at any wanted time and of the variations of the attenuation coefficient with latitude, altitude and solar cycle.
