| Abstract: | Photoelectron energy spectra have been measured on the layer compounds 1T?TaSe2 and 1T?TaS2 at various polar angles of emission. The azimuthal angle was set to select only those photoelectrons propagating in a plane containing the ГMLA points of the Brillouin zone. The results are used to map energy-vs-wave-vector curves which are found to compare favorably with the first principles calculations of Mattheiss. |
