    Notes: Abstract The production and the performance of dielectric multilayer mirrors for Fabry-Perot interferometers from 20000 Å to 2350 Å are described. Details of the evaporation apparatus and techniques are given. The optical data — reflection factor, absorption factor and flatness — are represented graphically and discussed. For all wavelength cryolite served as low refractive material. The high refractive materials used were ZnS for wavelengths from the infrared to λ〉4100 Å, Sb2O3 for λ between 4200 Å and 3200 Å and PbF2 for the shorter wavelengths to λ=2350 Å. For PbF2 an exciton-band at 2190 Å has been found.

    Mass differences and vector currents (1967)

    Notes: Abstract Hadron mass differences are related to the divergences of the weak hadronic vector currents. The nearly conservedSU(3)-charges are used to understand the approximate validity of mass formulae. We present a simple argument —involving the formal quark structure of the relevant operators —for octet dominance and predict equald/f-ratios for the strong mass differences and the leading part of the electromagnetic mass splitting. Furthermore, mass formulae connecting differentSU(3)-multiplets are derived. A remarkable universality property of the coupling of the various particles to the divergences is observed by which even baryon and meson mass differences are related.
