Abstract
The QCD spectral sum rules in the presence of the external electromagn etic field F-mu nu are used to calculate the magnetic moments of Sigma (c) and Lambda(c). Our results are mu(Sigma c)(+)+=(2.1+/-0.3)mu(N), m u(Sigma c)(+)=(0.6+/-0.1)mu(N), mu(Sigma c)(0)=(-1.6+/-0.2)mu(N), and mu(Lambda c)=(0.15+/-0.05)mu(N). [S0556-2821(97)00723-6].
