Abstract
A new type of correlation between the spin and momentum of an electron arises in an asymmetric quantum well upon photoexcitation. Even if th e exciting light is unpolarized, the expectation value of the electron spin turns out to be nonzero. It is directed perpendicular to the ele ctron quasimomentum in the plane of the well. A longitudinal magnetic field disrupts the correlation, as can be seen in the intensity of the hot luminescence.
