✦ Synopsis

The results of ESR investigations carried out on T-irradiated Ag-doped lithium sodium sulphate (LiNaSO,) at LNT (77 K) are reported here. Two different centres of Ag (Ag °, Ag 2 +) have been observed at 77 K. In the case of Ag e+ the parameters are 9xx = 2.071 + 0.001, 9ry = 2.102 + 0.001, 9= = 2.402 +_ 0.001, Axx = 18 _+ 1 G, Ary = 20 +_ 1 G, and A~z = 26 + 1 G. The ground-state wave function has been found to consist primarily of dx2_y2 with a reasonable admixture of other orbitals. The extent of delocalization of the electron in the Ag 2 + has been estimated. For Ag o the parameters ,q and A are found to be isotropic.
