| 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. |
