The EPR of Cf3+ in octahedral symmetry and the nuclear dipole moment of 249Cf

Abstract
The EPR spectrum of the ground Γ6 state of 249Cf has been measured. The derived spin Hamiltonian parameters are g = 6.273±0.010 and A = (7.52±0.20) ×10−3 cm−1. The nuclear spin I = 9/2 has been confirmed and a value ‖μ‖ = 0.28±0.06μN for the nuclear dipole moment has been calculated from the hyperfine coupling constant.
