Interpretation

According to theory the angular scattering probability is given by

$\begin{displaymath} p(\theta) \propto4\sin^2 \eta_0 +25\sin^2\eta_2(3\cos^2\thet... ...a_0-\eta_2)(3\cos^2\theta-1)}_{\rm s+d interference term}, \end{displaymath}$

(1)

where $\eta_0$ and $\eta_2$ are the energy dependent s and d partial-wave phase shifts, respectively. A so-called coupled channels calculation gives the following values for $\eta_0$ and $\eta_2$ as function of the collision energy.

From these phase shifts we compute the following angular scattering probabilities (using Eq. (1))

These polar plots are in nice correspondence with our experimental observations 4.2.
