    Abstract

    The observational study of isotopic composition of ultra-heavy cosmic rays (UH-CRs) is the next important step after the ACE measurement of light isotopes, since no data has been available for both elemental and isotopic abundances in these cosmic rays. These abundances provide the clue for neutron capture nucleosynthesis, which is an essential for understanding the origin of galactic cosmic rays (GCRs). Long-duration-superpressure balloon over Antarctica capable of carrying large scientific payloads for a long period is under planning. A Large Isotope Spectrometer Array (LISA) made of solid-state track detectors (SSTD) will make the first measurement of the elemental and isotopic composition of GCRs for Z > 30 in the energy above 100 MeV/n.
