Cosmic Ray Isotope Spectrometer 5-250 MeV/n; Z=3-28; A=6-64; (Li-Ni)

NSSDCA ID: 1978-079A-12

Mission Name: ISEE 3
Principal Investigator:Prof. Edward C. Stone, Jr.


This experiment was designed to study the isotopic constitution of solar matter and galactic cosmic-ray sources, the processes of nucleosynthesis in the sun and in the galaxy, and astrophysical particle acceleration processes. The following species were resolved: lithium through nickel (Z from 3 through 28 and A from 6 through 64) in the energy range from 5 to 250 MeV/nucleon. The mass resolution was <0.3 u for Z<30.
