Investigation of Z ≥ 70 cosmic ray nuclei on the LDEF mission

The ultra heavy cosmic ray experiment (UHCRE) on the Long Duration Exposure Facility (LDEF) collected approximately 3000 cosmic ray nuclei with Z > 65 in the energy region E > 1.5 GeV/n. Almost 40% of the sample has been analysed to date. Details of the overall charge abundance pattern is outlined with estimates of the actinide abundance. Copyright (C) 1996 Elsevier Science Ltd
