### Abstract

The relativistic correction (RC) to the deuteron magnetic moment is calculated using the light-cone dynamics. The restrictions imposed by the angular condition on the electromagnetic current operator of the deuteron are discussed in detail. It is shown that the additive model for the current operator of interacting constituents is consistent with the angular condition only for the two first terms of the expansion of the "good" current component j_{+} = 1 2(j_{0} + j_{z}) in powers of the momentum transfer q. The RC to μ_{d} is expressed through the matrix element of the "good" component j_{+} and is found to be equal to (0.6-0.8) × 10^{-2} e h {combining short stroke overlay}/2m_{p}c for realistic NN potentials. Taking account of RC decreases essentially the discrepancy between the theoretical and experimental values of μ_{d}. Possible solutions of the angular condition for squared q-terms of the j_{+} current component are also discussed.

It is shown that the additive model for the current operator of interacting constituents is consistent with the angular condition only for the two first terms of the expansion of the "good" current component j+ = 1 2(j0 + jz) in powers of the momentum transfer q. The RC to μd is expressed through the matrix element of the "good" component j+ and is found to be equal to (0.6-0.8) × 10-2 e h {combining short stroke overlay}/2mpc for realistic NN potentials. Taking account of RC decreases essentially the discrepancy between the theoretical and experimental values of μd. Possible solutions of the angular condition for squared q-terms of the j+ current component are also discussed.
