摘要：

Proposed observation of coherent Bragg scattering by a lattice of vortices in uniformly rotating superfulid Helium is examined. We present the calculations of the cross section for different parameter values, as well as simulations of the detected intensity of the Bragg peaks for triangular arrays with varied degrees of distortion. Within this frame, a potentially feasible experiment is outlined to provide direct evidence of vortices with an atomic-scale core in superfluid Helium.
