We also investigate the space-time localisation and chirality of the corresponding eigenvectors.7 pages, Latex, 2 Postscript figures (included using epsfig) Conference Proceedings, 31st International Symposium Ahrenshoop on the Theory of Elementary Particles, Buckow, September 2-6, 1997High Energy Physics - Latticetext
