I 115 n nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) measurements have been performed on an antiferromagnet UIn3 with the cubic AuCu3 -type structure. The NQR frequency (Q) and Knight shift (K) of I 115 n in UIn3 have been estimated in the paramagnetic state from NMR experiments under applied field. The perpendicular component of transferred hyperfine coupling constant (A¥) has been deduced from scaled behavior of K to the static susceptibility (Ï). Under zero field, the observation of the NQR spectrum has led to an estimated Q of 11.8 MHz at 90 K. The temperature variation in the NQR relaxation rates (1/ T1) far above the NÃ
