This is the draft of the paper, “On Pair Production by Scattering of the γ ray,” co-authored by Yukawa and Shoichi Sakata, and contains the beginning part (up to Section 2) of the paper. This draft explains their research on the effect of electron-positron pair production by electromagnetic interaction prior to the elucidation on how cosmic rays lose their energy when they pass through a matter. When this paper was written (spring of 1935), Yukawa was engaged in the joint research with Shoichi Sakata after welcoming him to Osaka Imperial University. (Written by Yutaka Hosotani)
