摘要：
The two-dimensional angular correlation of electron-positron annihilation radiation (2D-ACAR) from the heavy-fermion dense Kondo system CeB6 was measured. The use of a recently developed filter procedure, designed to remove the characteristic positron-induced long range distortions that are frequently superimposed on the Fermi breaks, provided a good description of the Fermi surface features. Further, the results of a preliminary 2D ACAR study of the electronic structure of the heavy-fermion system Ceeu(6) are shown and compared with those obtained for the reference non-f-electron material LaCu6.
