A Korringa-Kohn-Rostoker phase-shift parametrization of the Fermi-surface geometry and Fermi velocities in Pd is presented based on new measurements cyclotron orbital areas effective masses using de Haas-van Alphen effect fields up to 13.2 T temperatures down 0.35 K. We report accurate symmetry direction all four sheets surface mass area open-hole sheet $L$ pockets. Comparison made band-theory radii velocities, enhancement effects due electron-phonon, electron-electron, electron-paramagnon...
Fermi radii and velocities are determined by deconvoluting de Haas---van Alphen data. Comparison of these data with accurate augmented---plane-wave band-structure results establishes the reliability calculations allows a determination anisotropic many-body enhancement factor $\ensuremath{\lambda}(\stackrel{\ensuremath{\rightarrow}}{\mathrm{k}})$. The Fermi-surface average $〈\ensuremath{\lambda}〉$ 1.33 suggests large electron-electron contribution. Our $\ensuremath{\lambda}(k)$ provide...
Characteristics of older adult volunteers and nonvolunteers who were active in a community center's programs compared order to determine correlates voluntarism. Only two variables significantly differentiated: sex past patterns organizational participation. Findings suggest high degree consistency between present activity adults. Implications related pre-retirement planning the appropriate placement elderly post-retirement activities.
The detailed angular dependence of the Fermi radius ${\mathrm{k}}_{F}$, velocity ${\mathrm{v}}_{F}$(k), many-body enhancement factor \ensuremath{\lambda}(k), and superconducting energy gap \ensuremath{\Delta}(k), for electrons on surface Nb are derived with use de Haas--van Alphen (dHvA) data Karim, Ketterson, Crabtree [J. Low Temp. Phys. 30, 389 (1978)], a Korringa-Kohn-Rostoker parametrization scheme, an empirically adjusted band-structure calculation Koelling. is nonrelativistic...
Morale and Life Satisfaction measures were used as independent variables to compare elderly subjects' degrees of participation in an organized leisure program. In examining the first 6 months membership a community center 109 non-institutionalized aged, it was found that 42% became regular users age-segregated older adult program, 36% erratic users, 21% non-users. Upon comparing their morale life satisfaction ratings, low scores on these two be significantly related use services, while high...
