By angle-resolved photoelectron spectroscopy (ARPES) we first confirm that the Dirac cone at the surface of {\\alpha}-Sn (0 0 1) layers subsists after covering with Ag. Then we show that resonant spin pumping at room temperature from Fe through Ag into {\\alpha}-Sn layers induces a lateral charge current that can be ascribed to the Inverse Edelstein Effect[4-5].
