摘要：

The occupancies of the different atomic species in the L2(1) austenitic phase of the Cu66.9Zn23.7Al9.4 alloy have been determined by electron diffraction using the multi-slice least-squares method taking dynamical scattering into account. The 4a site (0, 0, 0) is occupied by aluminium and zinc, while the 4b site (1/2, 1/2, 1/2) is occupied by zinc and copper, in both cases in a random fashion.
