Figure 1

Convergence of the $\alpha d$ elastic scattering observables with screening radius $R$. The differential cross section and deuteron analyzing powers ${\mathit{iT}}_{11}$ and $T_{20}$ at 4.81 MeV deuteron lab energy are shown as functions of the c.m. scattering angle. Results obtained with screening radius $R=5$ fm (dotted curves), 10 fm (dash-dotted curves), and 15 fm (solid curves) are compared. Results without Coulomb (dashed curves) are given as reference for the size of the Coulomb effect. The calculations were performed with the $\alpha N$-I potential.Reuse & Permissions

Figure 2

Convergence of the $\alpha d$ breakup observables with screening radius $R$. The differential cross section and deuteron analyzing power $A_{\mathit{yy}}$ in selected kinematical configurations at 15 MeV α lab energy are shown as functions of the arclength $S$ along the kinematical curve. Results obtained with screening radius $R=10$ fm (dotted curves), 15 fm (dash-dotted curves), and 20 fm (solid curves) are compared. Results without Coulomb (dashed curves) are given as reference for the size of the Coulomb effect. The calculations were performed with the $\alpha N$-I potential.Reuse & Permissions

Figure 3

The differential cross section and deuteron analyzing powers at 4.81 MeV and 17 MeV deuteron lab energy. Results including the Coulomb interaction obtained with potentials $\alpha N$-I (solid curves), $\alpha N$-II (dotted curves), and $\alpha N$-III (dash-dotted curves) are compared. $\alpha N$-I results without Coulomb (dashed curves) are given as reference for the size of the Coulomb effect. The experimental 4.81-MeV data are from Ref. [7] for the differential cross section and from Ref. [5] for the spin observables, and the 17-MeV data are from Ref. [6].Reuse & Permissions

Figure 5

The differential cross section and deuteron analyzing power $A_{\mathit{xx}}$ of the $\alpha d$ breakup at 12 MeV deuteron lab energy in the $({25}^{°},{45}^{°},{180}^{°})$ configuration. Results obtained using the potential $\alpha N$-I with (without) Coulomb are shown as solid (dashed) curves. The experimental data are from Ref. [9].Reuse & Permissions
