Scientific paper

Synthesis of chemical elements at conditions of nuclear statistical equilibrium is investigated for the ultramagnetized astrophysical plasma in supernovae and near to neutron stars. For iron group nuclides, the magnetic modification of nuclear structure shifts a maximum of nucleosynthesis products towards smaller mass numbers approaching titanium. Signals of 44Ti radioactive decay in the gamma-spectra of the supernova remnant Cassiopeia A were revealed from the integral IBIS/ISGRI observational data. The gamma-ray fluxes for 44Sc* lines with energies 67.9 and 78.4 keV are determined. The relationship between model and observational results is discussed.
