Abstract
We have studied the temperature dependence of two of the foul magnetic -field perturbed NQR lines in indium. Our results indicate that the si gn of the internal electric field gradient (EFG) is positive, in accor d with the recent heat capacity measurements of the ISSP group and one recent theoretical prediction, We also discuss the implications of th e sign of the EFG on the use of indium as an absolute thermometer belo w 1 mK.
