B. Söderberg and L. Lönnblad Twist and Finite-Size Effects for the Source Method Zeitschrift für Physik C 42, 289-296 (1989) Abstract: We analyze the finite size effects for the source method in pure lattice gauge theory at weak coupling. They are found to be strongly suppressed by twisting the boundary conditions, for SU(3) by typically an order of magnitude. LU TP 87-16
