The time-dependent wave packet method was used to calculate the state-to-state differential cross sections for abstraction and exchange processes in the title reaction on the Kurosaki–Takayanagi potential energy surface [Kurosaki Y, Takayanagi T, J Chem Phys119:7838, 2003], with the reactant HBr initially in the ground rovibrational state. It is found that the trend in the product distributions is similar for abstraction and exchange processes, but the differential cross sections are very different. For the exchange reaction, the product is mainly scattered in the backward hemisphere for collision energy up to 2.0 eV, although forward scattering gradually shows up in high collision energies. While for abstraction reaction, the differential cross section changes substantially with the collision energy, moving from predominantly backward peaked at low collision energy to predominantly forward peaked at high collision energy. The rovibrational state resolved differential cross section at collision energy of 2.0 eV exhibits two peaks for the abstraction reaction, one is around the angle of 50°, and the other at 0°. It is found that the peaks around 50°, are below the corresponding maximum j' lines provided by the kinematic constraint model, while the forward-scattered peaks straddle both sides of the kinematic limit, and are likely contributed from both the direct and the migratory reaction mechanisms as proposed by Zare and coworkers.

We present a model of backward π+p, π−p, and π−p charge exchange scattering consistent with our earlier approach to forward π−p charge exchange and backward π+p. We consider two body differential cross section data which exhibits a dip–bump structure as well as nonzero polarization. This is explained in terms of a dominant Regge pole vanishing at the dip accompanied by a background. The background is primarily responsible for the large u behavior of the cross section which includes the rise after the dip. It is assumed that the presence of nonzero polarization dictates this behavior. We isolate the I = 3/2 amplitude in π−p backwards and determine the I = 1/2 amplitude from π+p backwards. A prediction for π−p → nπ0 follows.

Exchange Scattering

The differential cross section for pion charge-exchange scattering from 12C is calculated using sum-rule techniques in order to investigate possible spin-dependent effects in proton–neutron correlations. The resulting cross section proves to be quite insensitive to such effects under the usual assumptions concerning the correlation function.
