We have investigated the elastic and inelastic scattering in the $Cl+D2$ system as a probe of the coupling between $Cl(2P3/2)+D2$ potential energy surface and the $Cl\ast (\mathrm{<mrow\; data-mjx-texclass="ORD">2</mrow>}P1/2)+D2$ potential energy surface. Our experiments utilize a newly constructed cross molecular beam machine with velocity map ion imaging detection to probe all scattering into the $Cl\ast (\mathrm{<mrow\; data-mjx-texclass="ORD">2</mrow>}P1/2$) channel at a collision energy of 1700 Collisions between $Cl(2P1/2)$ which result in a non-adiabatic transition to the upper spin-orbit potential energy surface must partition $881cm-1(=ES.O.,Cl)$ less energy into relative translation. Our ion spin-orbit changing collisions in the $Cl+D2$ system and allow for an estimate of the total cross section for such collisions.
