Fig. 3
Amplitudes of the four types of reflections (\(R_{N\uparrow \uparrow }\), \(R_{N\uparrow \downarrow }\), \(R_{A\uparrow \uparrow }\), \(R_{A\uparrow \downarrow }\)) as functions of the incident electron energy E and the incident angle \(\alpha\). The parameters used in the calculation are \(L_1=0.1\xi\), \(L_2=0\), \(\mu =\mu _j=100\Delta _0\), \(U_0=0\), \(\varphi _n=\theta _n=0\), \(\varphi _m=\theta _m=0.5\pi\), (a-d) \(h_n=0.5\mu\), (e-h) \(h_n=\mu\).
