The neutron capture cross section of the unstable nucleus W-185 has been
derived from experimental photoactivation data of the inverse reaction
W-186(gamma, n) W-185. The new result of sigma = 687 +/- 110 mbarn
confirms the theoretically predicted neutron capture cross section of
W-185 of sigma approximate to 700 mbarn at kT = 30 keV. A neutron
density in the classical s-process of n(n) = (3.8(-0.9)(+1.1)) x 10(8)
cm(-3) is derived from the new data for the W-185 branching. In a
stellar s-process model, one finds a significant overproduction of the
residual s-only nucleus Os-186.
