It is shown for the first time that a curved single crystal can capture particles in the channeling regime for angles exceeding the Lindhard angle. 1-GeV protons were captured during channeling by (111) and (110) planes and by (110) axis along the entire length of a 1-cm silicon single crystal curved along a radius of 46 cm in the entire angular range up to 20 mrad.
