Abstract

We have measured the predicted orientation induced by first-order Stark effect on

sp

coherent levels of

{He}^{+}

and H excited by a 100-keV

{Na}^{+}

beam impinging on a cell filled with He or

H_{2}

. We discuss the mechanism of production of

sp

coherence by dissociative excitation of

H_{2}

.
