IMP 8 Cosmic Ray Nuclear Composition (CRNC) hourly count rates of heavy nuclei
ReleaseDate
2021-03-11 18:39:11Z
Description
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.)

original CRNC PI, and Clifford Lopate/UNH, current PI.
