The variation in the latitude dependence of cosmic rays at 307 G/CM2 during solar cycle No 20

Description
When results from latitude surveys at 307g/cm2 during 1964, 1966, 1969, 1971 and 1974 are intercompared for detectores of cosmic rays, the variation in time of the rigidity dependence of primary cosmic rays is obvious. The neutron monitor results are represented in its rigidity dependence by the force field parameter k2/phi. These modulation results are compared with those obtained from the latitude dependence of the counting rate of the neutron moderated detector (NMD), which shows a much stronger latitude dependence than the neutron monitor.

Abstract (German)
Wenn man die Ergebnisse von breitenabhaengigen Untersuchungen bei 307g/cm2 (225 mm Hg Luftdruck) von 1964, 1966, 1969, 1971 und 1974 fuer die Detektoren der kosmischen Strahlen vergleicht, ist die zeitliche Aenderung der Haerteabhaengigkeit der primaeren kosmischen Strahlen offenkundig. Die Ergebnisse von Neutronendetektoren mit ihrer Haerteabhaengigkeit werden durch einen Kraftfeldparameter K2/phi beschrieben. Diese Modulationsergebnisse werden mit jenen verglichen, die man aus der Breitenabhaengigkeit der Zaehlrate von neutronenmoderierten Detektoren gewinnt, die eine viel staerkere Breitenabhaengigkeit zeigen als Neutronendetektoren.
