Abstract The contributions of the multipole transitions to the opacity of hot dense gold plasma are taken into account by using an average-atom model. The influences of the E2, E3 and E4 transitions on the Rosseland opacity are studied, respectively. Comparisons with Miao s calculation have been made. It shows that using the Taylor series to account for the multipole transitions is no longer valid since ikr is not much smaller than the unit when the photon energy goes very high.
