In this paper we characterise the minimisers of a one-parameter family of nonlocal and anisotropic energiesdefined on probability measures in, with. The energyconsists of a purely nonlocal term of convolution type, whose interaction kernel reduces to the Coulomb potential forand is anisotropic otherwise, and a quadratic confinement. The two-dimensional case arises in the study of defects in metals and has been solved by the authors by means of complex-analysis techniques. We prove that for, the minimiser ofis unique and is the (normalised) characteristic function of a spheroid. This result is a paradigmatic example of the role of the anisotropy of the kernel on the shape of minimisers. In particular, the phenomenon of loss of dimensionality, observed in dimension, does not occur in higher dimension at the valuecorresponding to the sign change of the Fourier transform of the interaction potential.
