The near threshold photoionization cross section of atomic scandium
, 1996 A photoionization cross-section calculation for atomic scandium, which has the LS coupled ground-state configuration ([Mg] 3p(6)3d4s(2)) [D-2] is performed in the formalism of many-body perturbation theory for photon energies ranging from the first ...

Smaller is better: nanobodies meet NMR
FEBS Letters, EarlyView.Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Atomic photoionization cross sections beyond the electric dipole approximation [PDF]
The Journal of Chemical Physics, 2019 A methodology is developed to compute photoionization cross sections beyond the electric dipole approximation from response theory, using Gaussian type orbitals and plane waves for the initial and final states, respectively. The methodology is applied to compute photoionization cross sections of atoms and ions from the first four rows of the periodic ...

FEBS Letters, EarlyView.Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Formation of protonium and positronium in atomic collisions [PDF]
, 2001 A minimum-norm method has been developed for solving the coupled integro-differential equations describing the scattering of positrons by one-electron targets in which the rearrangement channels for positronium formation have been explicitly included ...

Measurement of the absolute 4d-photoabsorption cross section of atomic barium
, 1995 The absolute photoabsorption cross section of atomic barium in the region of the 4d-giant resonance (80-140 eV) has been determined. The vapour density in the absorbing metal vapour column, required for the determination of the absolute cross sections ...
