Figure 1

Coplanar cross sections and analyzing powers as a function of ${\theta }_1$ (${\theta }_2$) for ${\theta }_2$ (${\theta }_1)={16}^{°}$ and ${\theta }_{\gamma }={145}^{°}$. The long-dashed, dashed, and solid curves correspond to results obtained from the ROBE model for pseudoscalar coupling (using on-shell $p\gamma p$ vertex), pseudovector coupling (using on-shell $p\gamma p$ vertex), and pseudovector coupling (using the off-shell $p\gamma p$ vertex), respectively. The data, as well as the microscopic (dashed-dotted curves) and soft-photon (dotted curves) theoretical results, are from Ref. 1.Reuse & Permissions

Figure 2

Coplanar cross sections and analyzing powers for symmetric proton angles as a function of ${\theta }_{\gamma }$. The identification of the respective curves is the same as in Fig. 1. The data, as well as the microscopic and soft-photon theoretical results, are from Ref. 2.Reuse & Permissions

Coplanar cross sections and analyzing powers as a function of ${\theta }_2$ for fixed ${\theta }_1$ and ${\theta }_{\gamma }$. The identification of the respective curves is the same as in Fig. 1. The data, as well as the microscopic and soft-photon theoretical results, are from Ref. 3.Reuse & Permissions
