摘要：

We measure accurate values of the inter-quark potentials on a 48(3)56 lattice with SU(2) pure gauge theory at beta = 2.85. The scale is set by extracting the string tension - we obtain square-root Ka = 0.063(3) at beta = 2.85. From a careful study of the small-R potentials in the region 2 GeV < R-1 < 5 GeV, we extract a running coupling constant alpha (R).
