Nuclear orientation study of¹⁸²Ta in 2H-TaS₂

Abstract

Quadrupole-interaction nuclear orientation experiments have been performed on¹⁸²Ta (j^π=3⁻¹; T_1/2=115d) in 2H-TaS₂. γ-anisotropies up to ∼ 30 % have been observed at a temperature of ∼ 8 mK, which, however, is only about half of the value expected taking into account known results of TDPAC measurements on¹⁸¹Ta in 2H-TaS₂. In principle, matrices of dichalcogenides could be well suited for nuclear quadrupole resonance on oriented nuclei (NQR-ON) experiments.
