The research program has included studies of the composition and the energy spectrum of the primary cosmic radiation and studies of nucleus-nucleus interactions at medium and high energies. The investigations have been performed with nuclear emulsions which have been exposed to the primary radiation in high altitude balloon flights or in sounding rocket flights. The investigations of the primary radiation have mainly been concentrated on studies of the composition of the flux of heavy primaries. One of the main purposes of our research has been to investigate the composition of the radiation in different energy intervals. An investigation of the isotopic composition of the carbon in the primary flux was also performed. The studies of the nucleus- nucleus collisions have been concentrated on such interactions in which the primary particles either have had an energy larger than 2 GeVnucleon or have had an energy in the interval 100 - 400 MeVnucleon. Comparisons between nucleus-nucleus interactions have been performed in both energy intervals.
