Abstract

Forbidden hyperfine transitions are observed in the electron spin resonance spectrum of divalent Mn55 ion in NaCl single crystal for a particular associated pair. From the measurements of the M = + 1/2 → −1/2, Δm = ± 1 transitions the parametersQ′ and Q″ of the nuclear electric quadrupole part of the spin-Hamiltonian Ho = Q′ [Iz 2 − 1/3 I (I + 1)] + Q″ (Ix 2−Iy 2) are found to be + 1.70 × 10−4 cm.−1 and +0.16 × 10−4 cm.−1 respectively.
