We consider momentum resolved tunneling between a Luttinger liquid and a two-dimensional electron gas as a function of transverse magnetic field. We include the effects of an anomalous exponent and Zeeman splitting on both the Luttinger liquid and the two-dimensional electron gas. We show that there are six dispersing features that should be observed in magneto-tunneling, in contrast with the four features that would be seen in a noninteracting one-dimensional electron gas. The strength of these features varies with the anomalous exponent, being most pronounced when gamma(rho)=0. We argue that this measurement provides an important experimental signature of spin-charge separation.
