Measurement of elemental abundance of very low energy solar cosmic raysHeavy interplanetary particles (Z from 3 to 30) have been observed during a solar flare period between October 29 and November 4, 1972. The nuclear abundance has been determined by a two parameter analysis of a thin window proportional counter - solid state detector device aboard the Explorer 47 (IMP-7) satellite. Energy spectra are given for C, O and Fe. The elemental abundance relative to oxygen is determined for carbon, neon, magnesium, silicon and the iron group in the energy range 0.62 to 6.9 MeV/nucleon. For the Fe/O ratio no energy dependence could be observed within the error limits.
