Studies of the cosmic ray latitude effects
A cosmic ray experiment in a B-29 airplane conducted through a wide range of latitudes at high altitudes is described. The chief experimental result is that the various cosmic ray components behave in quite similar fashion and hence are probably produced by the same primaries in a type of interactio...
