Abstract
An experiment is proposed to test the recent suggestion that the conduction electrons in some metals can spontaneously develop a nonzero average helicity. The photon pair momentum distribution resulting from positron annihilation in such metals is shown to be asymmetric in the direction of positron polarization. This asymmetry should be easily detectable by present experimental techniques.
