Abstract
The specific heat of polycrystalline indium has been measured to well below 1 mK to determine the nuclear quadrupole interaction and to stud y the nuclear spin-spin interaction. The sign of the electric field gr adient eq is found to be positive instead of the negative sign reporte d previously. This sign agrees with a recent calculation based on band cheery. The local field coming from the nuclear spin-spin interaction is determined to be b(int) = 43 +/- 5 mT in indium.
