The radiative absorption, charge-exchange scattering, elastic and inelastic scattering of a π+ meson by the deuteron are calculated in conventional weak-coupling theory for the pseudoscalar field with both direct and gradient coupling. The nucleon-nucleon interaction is treated phenomenologically and the "impulse" approximation employed. The behavior of the ratio $$\frac {σ_{nonradiative}}{σ_{radiative}}$$ for the PS theory is different from that for the PV theory. Further, the charge-exchange scattering of a PS meson exhibits a minimum for forward scattering for both types of coupling but otherwise mirrors the behavior of the charge-exchange cross section for a neutron target. The elastic and inelastic scattering cross sections are comparable for an incident 25-Mev meson, and small energy transfers to the deuteron are favored, in contrast to the case in which the target nucleus is more complex.
