Abstract
We analyze the possibilities of pairing between two different fermion speci es in asymmetric matter at low density. While the direct interaction allows pairing only for very small asymmetries, the pairing mediated by polarizat ion effects is always possible, with a pronounced maximum at finite asymmet ry. We present analytical results up to second order in the low-density par ameter k(F)a. (C) 2001 Elsevier Science B.V. All rights reserved.
