The BFS method for alloys is applied to the study of the Cu-Pd system. Emphasis is made on the ability of the method to describe these properties on the basis of a minimum set of BFS universal parameters that uniquely characterize the Cu-Pd system.

Atomistic modeling of the site substitution behavior of Pd in NiTi (J. Alloys and Comp. (2004), in press) has been extended to examine the behavior of several other alloying additions, namely, Fe, Pt, Au, Al, Cu, Z r and Hf in this important shape memory alloy. It was found that all elements, to a varying degree, displayed absolute preference for available sites in the deficient sublattice. However, the energetics of the different substitutional schemes, coupled with large scale simulations indicate that the general trend in all cases is for the ternary addition to want to form stronger ordered structures with Ti.

High-spin states in ' Tl have been populated through the ' Ho( Si,4n) reaction and studied with inbeam y-ray spectroscopy techniques. Both oblate and prolate structures associated with the i '2 proton orbit are confirmed and extended to higher spins ( '2 and 2', respectively). However, only the oblate structure related to the mhhas been observed meaning that the associated prolate structure is nonyrast contrary to expectation. This experimental result points clearly to a large amplitude of (~h 2 ) in the wave function of the prolate minimum of " Hg.
