Defect Trap** in Iron Studied by NMR/ON
The first recovery-stage in α-Fe at 120 K is assumed by most authors to be associated with the long range migration of interstitials. The nature of the defect which is mobile in stage III, at 220 K, is the sub...

Observation of a cubic defect in nickel by means of β-NMR on oriented114In nuclei
The hyperfine field of substitutional and defect-associated In atoms in Ni has been determined by observing the radiative destruction of β-asymmetry in the decay of114In. It is argued that the associated defect i...

Generalized polarizabilities of the nucleon studied in the linear sigma model
The generalized polarizabilities of the nucleon have been calculated in the one-loop approximation of the linear sigma model in the limit of infinite sigma mass. In particular, we have investigated the spin-in...

Hyperfine induced magnetic order in Pr: Neutron diffraction at mK temperatures
With elastic neutron scattering we investigated the magnetic reflections of a single crystal of pure Pr in the temperature range down to 8 mK. We found a double peak structure consisting of a narrow antiferrom...

Generalized polarizabilities of the nucleon studied in the linear sigma model (II)
In a previous paper virtual Compton scattering off the nucleon has been investigated in the one-loop approximation of the linear sigma model in order to determine the 3 scalar generalized polarizabilities. We ...

Dispersion Theoretical Analysis of the Nucleon Spin Polarizabilities
The spin polarizabilities of the nucleon have been calculated from pion photoproduction data using forward dispersion relations. The feasibility of an experimental determination of these structure constants is...

Soft and hard Pomeron in the structure function of the proton at low x and low \(Q^2\)
We study inclusive electroproduction on the proton at low x and low \(Q^2\) using a soft and a hard Pomeron. The contribution of the soft Pomeron is based on the Stochastic Vacu...

Semi-exclusive production of photons at HERA
We study the feasibility of measuring the semi-exclusive photon production \(\gamma + p \to \gamma + Y\) at HERA. The cross section of photons produced at large transverse momen...

Hyperdeformation and clusterization in the actinide region
The 233U(d,pf)234U, and the 235U(d,pf)236U reactions have been studied with high energy resolution. The observed fission resonances were described as members of rotational bands with rotational parameters charact...

Experiments on the Magnetism of Sc Implanted into Metals
The study of dilute Sc impurities in either heavier d-transition metals or in alkali metal hosts is difficult due to their limited solubility; however, the large host-impurity mismatch in these systems makes them...

Detailed spectroscopy in the superdeformed second minimum of 240Pu
Spectroscopic studies in the superdeformed shape isomer of 240Pu using γ-spectroscopy, conversion electron spectroscopy and transmission resonance spectroscopy have been performed. In a high-resolution and high-e...

Dispersion relation formalism for virtual Compton scattering off the proton
We present in detail a dispersion relation formalism for virtual Compton scattering (VCS) off the proton from threshold into the Δ(1232)-resonance region. Such a formalism can be used as a tool to extract the ...

Supersymmetry in the spectra of complex atomic nuclei
Evidence is observed for the existence of supersymmetry from the study of the odd-odd nucleus 196Au using the 197Au( \(\vec d\) ...

Towards complete spectroscopy of 193Os
Strong evidence for the existence of supersymmetry in atomic nuclei has been found in the quartet of nuclei 194,195Pt, 195,196Au [1–3]. Our attention is now focused a second quartet of nuclei, that is 193,194Ir,

Twist-3 single-spin asymmetries in semi-inclusive deep-inelastic scattering
The single-spin asymmetries for a longitudinally polarized lepton beam or a longitudinally polarized nucleon target in semi-inclusive deep-inelastic scattering are twist-3 observables. We study these asymmetri...

Overview of Recent Model Calculations of Single Spin Asymmetries
Over the past years a lot of progress has been made in the understanding of single spin asymmetries in hard scattering processes. We briefly review this subject, covering the non-vanishing of time-reversal odd...

Open AccessTransverse-momentum-dependent parton distribution/fragmentation functions at an electron-ion collider
We present a summary of a recent workshop held at Duke University on Partonic Transverse Momentum in Hadrons: Quark Spin-Orbit Correlations and Quark-Gluon Interactions. The transverse-momentum-dependent parto...
