	abstract = {In this paper, we report observation of the vortex lattice above the surface of high-temperature superconductors Pr 2 - x Ce x CuO 4 - δ using beta-detected \{NMR\} ( β -NMR) of Li + 8 implanted in a 40\&$\#$xa0;nm thick Ag overlayer. The resonance in Ag broadens dramatically below the transition temperature T c as expected from the vortex lattice in the underlying superconductor. However, the lineshape is nearly symmetric with the absence of a high-field tail and exhibits a slight positive shift of the average field below T c .},
