  The structure of a proximity induced vortex core in a two-dimensional (2D)
metallic layer covering a superconducting half-space is calculated. We predict
formation of a multiple vortex core characterized by two-scale behavior of the
local density of states (LDOS). For coherent tunnelling between the 2D layer
and the bulk superconductor, the spectrum has two subgap branches while for
incoherent tunnelling only one of them remains. The resulting splitting of the
zero-bias anomaly and the multiple peak structure in the LDOS should be visible
in the tunnelling spectroscopy experiments.
