Superfluidity in Nuclear Matter — •Jan Kuckei and Herbert Müther — Institut fr Theoretische Physik, Universität Tübingen

Superfluidity plays an important role in the physics of nuclear matter. It is paramount for several properties of neutron stars, such as their cooling mechanism and certain dynamical features.

We present calculations of the superfluid pairing gap for isospin T=0 and isospin T=1 pairing. The sensitivity of the pairing correlations on the nucleon-nucleon interaction as well as the determination of the single-particle spectra are discussed in detail. For asymmetric nuclear matter we observe proton and neutron pariring with a total momentum different from zero.
