By high oxygen pressure synthesis, La1.82Ca1.18Cu2O6 was found to be superconducting (TC(zero) =49K). Using the conventional spin-echo method, a nuclear resonance experiment is conducted on a powder La1.82Ca1.18Cu2O6 sample. Nuclear Quadrupole Resonance (NQR) spectrum of 139La at 4.2K is obtained for the first time. The quadrupolar frequency (vQ) was estimated to be 5.9±0.1 MHz. The broad spectrum (the full width at half maximum intensity is about 2.5MHz) indicates that the electric field gradient (EFG) is distributed. Spin-lattice relaxation time (T1) is also discussed.
