摘要: The isotopic composition and amounts of krypton extracted from four stone meteorites one sample meteoritic troilite have been measured. For the two chondrites Bruderheim Abee, phase Canyon Diablo, was found to be different in atmosphere. isotope anomalies can explained by effects due present-day cosmic rays, i.e., spallation reactions on rubidium strontium neutron capture bromine selenium.
