- 論文の詳細を見る
The three dimensional electron-positron momentum densities have been obtainedon Ti and Zr from measurerrnents of two dimensional angular correlation of positronannihilation radiation followed by an image reconstruction technique based on directFourier transformation. Augmented-plane wave band strttcture calculations havebeen carried out and the results are compared with the experiments. Agreement be-tween the experiment and the theory leads to a conclusion that both Ti and Zr haveelectron surface sheets which are centered at H and hole surface sheets which are run-ning along the T-A axis.positron annihilation, Fermni surface, experiment, theory, band structure calcula-tions, 2D ACAR, electron momentum density, three dimensional reconstruc-lion, titanium, zirconium
