Abstract：
The spectra of primary cosmic ray nuclei are fitted from experimental data under 10¹⁴eV and extrapolated to their bending energies. The primary cosmic ray composition above 10¹⁴eV is deduced according to the rigidity cut off model by selecting an appropriate bending energy for proton so that the sum of various nucleus components is consistent with the experimental total particle spectrum. The method used is independent on the behaviour of hadronic interaction.
