This report presents the final results of the proton and the helium spectra in the energy range between 10 and 500 TeV/nucleon obtained by RUNJOB experiments as trans-Siverian long duration balloon. A proton with PeV energy was directly detected in 1995 campaign. This is the first detection of proton event more than 1015 eV in direct observation. Our proton spectrum is in good agreement with other results such as JACEE and SOKOL, but the intensity of the helium component is nearly half that obtained by them, while it agrees with MUBEE. The slopes of the spectra of these two elements in RUNJOB are almost parallel with power index of 2.7?2.8 in the energy range 10?500 TeV/nucleon. These results suggests simply acceleration and propagation mechanism of cosmic rays depending on particle rigidity.
