D. Osullivan et al., INVESTIGATION OF Z-GREATER-THAN-OR-EQUAL-TO-70 COSMIC-RAY NUCLEI ON THE LDEF MISSION, Radiation measurements, 26(6), 1996, pp. 889-892
The ultra heavy cosmic ray experiment (UHCRE) on the Long Duration Exp
osure Facility (LDEF) collected approximately 3000 cosmic ray nuclei w
ith Z > 65 in the energy region E > 1.5 GeV/n. Almost 40% of the sampl
e has been analysed to date. Details of the overall charge abundance p
attern is outlined with estimates of the actinide abundance. Copyright
