• Pion production cross sections by neutrinos and antineutrinos ν+p→p+e^-+π^+, ν^^-+p→p+e^++π^-, are calculated in the lowest order perturbation theory for neutrino energies of 0.5 Bev, 1 Bev, 3 Bev, 5 Bev and 10 Bev in the laboratory system. The results are shown in Table I, in which we see that the "inelastic" cross section ν+p→p+e^-+π^+ is much smaller than the "elastic" cross section at 1 Bev, while the former is about 10 times larger than the latter at 10 Bev. It is also found that the contribution of the Gell-Mann current is appreciable. The interference term between the nucleon current and the Gell-Mann current turns out to be large enough to compete with the direct terms. The antineutrino cross sections are smaller than those of neutrino approximately by a factor of two and the main difference between them comes from the interference term.
