Abstract
This article presents a calculation of shear relaxation times of monatomic fluids covering both the liquid and dense‐gas phases. The times, which are not experimentally accessible at present, are calculated using low‐frequency viscosity data and theoretical estimates of the high‐frequency elastic moduli which were produced earlier by the authors. Numerical values of the relaxation times at various temperatures and densities are presented graphically. Except at very low densities, the times are on the order of 10−13 sec.
