Abstract Current experimental data provides constraints upon the nuclear excitation functions for 160 P + p14 N , 15 N , 13 C and their progenitors. These cross sections, combined with the elemental and isotopic ratios measured at Earth, are used in a complete model of cosmic ray propagation to study the source composition. The 14 N O ratio in the cosmic ray source matter is appreciably less than its value in the solar system, while the source 13 C C ratio is in agreement with solar system or local galactic material but not with matter near the galactic center.
