The three-dimensional electron-positron momentum densities in paramagnetic Cr and W are reconstructed from measurements of two-dimensional angular correlation of positron annihilation radiations (2D-ACAR) by the image reconstruction technique based on a direct Fourier transformation. The experimental momentum density for paramagnetic Cr and W shows the contribution of the Fermi surface sheets; the electron surface at r, the hole surface at H, the hole surface at N. The Fermi surface topology obtained from the present results agrees with the theory and other experiments.La trois demensionne electron-positron impulsion densite de paramagnetetique Cr et W a ete reconstruit de mesures de deux dimensionne angulaire correlation de position aneantissement radiations (2D-ACAR) par la image reconstruction technique base sur une directe Fourier transformation.

The Fermi surface (FS) of molybdenum is investigated with high precision &(0.2 to 0.5%) by means of the radio-frequency size effect (RFSE) on thick samples. The anisotropy of extremal dimensions of all sheets of the FS of molybdenum in the {loo} and { 110) planes is measured.High precision of the measurements allows to separate effectively RFSE lines stipulated by the FS sheets with close dimensions, and to measure reliably the gaps between the tightly situated FS pieces of molybdenum. With the aid of computer calculations the analytical description of the FS is obtained in form of a series in spheric and cubic harmonics. The derivatives aS/ak, for various directions k, are calculated with a computer according to these data.

“…An orbit centre and plane would be manually specified, then the algorithm would perform a series of "stepping" and "returnto-surface" operations as a function of rotation angle around the orbit centre to determine the cross-sectional area via Simpson's-rule integration [7]. This approach was later expanded to included trapezoidal-rule integration for orbits which are multivalued at certain angles around the orbit centre [8]. While such an approach works well when one knows which orbits are extremal (and the locations of the associated orbit centres), topologically-complicated Fermi surfaces can have extremal orbits that are not obvious from visual examination of the surfaces.…”

A new algorithm for extracting de Haas-van Alphen frequencies and effective masses from calculated band energies is presented. The algorithm creates an interpolated kspace "super cell," which is broken into slices perpendicular to the desired magnetic field direction. Fermi surface orbits are located within each slice, and de Haas-van Alphen frequencies and effective masses are calculated. Orbits are then matched across slices, and extremal orbits determined. This technique has been successful in locating extremal orbits not previously noticed in the complicated topology of existing UPt 3 band-structure data; these new orbits agree with experimental de Haas-van Alphen measurements on this material, and solidify the case for a fullyitinerant model of UPt 3 .
