LARELKIN Two-body relativistic kinematics code Version 1.12.1

This interactive and self-explaining computer program allows the relativistic calculation of the kinematics parameters of two-body reactions. Calculations for reactions with masses that are available in the 2012 International Atomic Mass Tables do not require an external input of mass values. Other reactions require the preparation of an appropriate data input file. Together with the FORTRAN95 source file, an executable for MSWindows is provided, and all the auxiliary files, as well.
