ZCB This data set contains hourly, spin-averaged count rates of heavy nuclei, and of particles penetrating the anticoincidence sensor, from the IMP8 Cosmic Ray Nuclear Composition experiment of U. Chicago and UNH. Included are rates of CNO nuclei at E.LT.80 MeV/n and E.GT.80 MeV/n, of Z.GT.8 nuclei at "low" and "high" energies, and of penetrating particles (protons with E.GT.106 MeV, etc.) Acknowledge the late John A.
