Tetragonal Boron and Borides with Similar Structuresubstitution reaction with BCl.. In the infrared spectrum of powdered .-boron, two bands can be assigned to vibrations of boron atoms belonging to the same icosahedron. In BeB. and in tetragonal boron, additional bands are observed which belong to the stretching frequencies of the bonds between neighboring icosahedrons.

Some Results of the Band Structure Calculation of Rhombohedral Boron by the K·p-Methods not possible to determine where the band edges are located, where in the Brillouin zone the transitions between valence and conduction band take place, and whether these transitions will be direct or indirect. Optical measurements together with our group theoretical results could possibly lead to a band model for boron.

In some cases, the final product was then zone-refined. Analytical results from emission and mass spectroscopy are given. Advantages and disadvantages of the bromide and iodide processes are compared.

Feigls naturalistische Moralkonzeption,pped holes precedes that of the trapped electrons. The shape of the thermal stimulation curve for the photocurrent in phase 3 of low-temperature experiments depends on the color of the visible light used for the excitation during phase 1. This is probably related to the increase of the absorption co
