title: Exchange interaction between nuclear spins.
abstract: We describe the developments in the determination of exchange interaction between nuclear moments in a metal. We discuss two techniques, the isotopic interference and higher harmonics of Larmor precession, both techniques determine the sign as well as the magnitude of the exchange constant. In addition, we briefly discuss the possibility of experiments at negative temperatures providing additional information about the space dependence of the exchange interaction.
