Origin and composition of ultrahigh energy cosmic rays.
Author and Affiliation:
Stecker, F. W.(NASA Goddard Space Flight Center, Laboratory for Space Physics, Greenbelt, Md., United States)
Abstract: Suggestion that, under certain circumstances, the absence of an apparent flattening of the ultrahigh energy cosmic ray spectrum at an energy level above 3 x 10 to the 18th power eV may have implications concerning the origin of ultrahigh energy cosmic rays (UECR). On the basis of the discussion presented, it seems that a heavy composition is indicated. It is therefore concluded that recent air-shower studies seem to indicate the resurrection of the galactic origin model.
