Herwig Schopper - Scientific Publications#

More than 200 original articles in the fields of optics, nuclear physics and elementary particle physics. Some of the most important publications are quoted below:

1. Optics and solid state physics

R.Fleischmann und H.Schopper, Die Bestimmung der optischen Konstanten und der Schichtdicke absorbierender Schichten mit Hilfe der Messung der absoluten Phasenänderung, Z.Physik 129,285 (1951)
(First method to measure the absolute phase on thin metal layers)

H.Schopper, Zur Deutung der optischen Konstanten der Alkalimetalle, Z.Physik 135, 163 (1953)
(It was shown that the anomalous optical behaviour of alkali metal layers does not require a special state of the metal as was claimed by the Pohl school)

2. Nuclear physics

H.Schopper, Circular polarisation of gamma-rays: Further proof for parity failure in beta-decay, Phil.Mag. 2, 710 (1957)
(One of the experiments discussed by Lee and Yang, but thought not to be feasible. Experiment showed for first time that helicities of neutrino and antineutrino are opposite)

G.Clausnitzer, R.Fleichmann und H.Schopper, Erzeugung eines Wasserstoffatomstrahles mit gleichgerichteten Kernspins, Z.Physik 144, 336 (1956)
(First realisation of a source of polarised nuclei)

H.Schopper and S.Galster, The circular polarisation of internal and external bremsstrahlung, Nucl.Phys. 6, 125 (1958)
(First experiment to show circular polarisation of internal bremsstrahlung in beta-decay)

3. Accelerator Technology

J.Halbritter, R.Hietschold, P.Kneisel, and H.Schopper, Coupling losses and the measurement of Q-values of superconducting cavities, KFK-report Karlsuhe 3/86-6 (1968)
(Early paper to study superconducting cavities for accelerators and particle separators)

4. Elementary Particle Physics

R.M.Littauer, H.Schopper, R.R.Wilson, Formfactors of the proton and neutron, Phys.Rev.Lett. 6, 286 (1961)
(It was shown that the original measurements of formfactors by Hofstadter were wrong)

Behrend et al., Elastic electron-proton scattering at momentum transfers up to 110 fermi-2 ,N uov.Cim. 48,140 (1967) and other publications

J.Engler, W.Flauger, B.Gibbard, F.Mönnig, K.Runge and Herwig.Schopper, A total absorption spectrometer for energy measurements of high-energy particles, Nucl.Instr.Meth. 106, 189 (1973)
(Invention of hadron calorimeter)

V.Boehmer et al., Neutron-proton elastic scattering from 10 to 70 GeV/c, Nucl.Phys. B91, 266 (1975) and other publications
(almost the only work on neutron-proton scattering at high energies, at the ISR and Serpuchov)
