Abstract: | An error in our previous paper (Clark, A. T., Madden, T. J. and Warren, P. B., 1996 Molec. Phys., 87, 1063) is corrected. This brings the results into agreement with the recent work of Grønbech-Jensen et al. (Grønbech-Jensen, N., Hummer, G. and Beardmore, K. M., Molec. Phys., 1997, 92, 941). |
