Coupled channel calculations for the reaction 15N(n, n′)15N∗

Physics Letters B, 1969
Abstract Elastic and inelastic scattering cross sections for the reaction 15 N(n, n′) 15 N ∗ are calculated from 0–12 MeV using the method of coupled channels within a 1 particle-1 hole configuration space. The results are compared with those obtained by other methods of calculation.

Quantitative NMR Spectroscopy under High Hydrostatic Pressure

Chemistry – A European Journal, EarlyView.
Solvent compression leads to an increase in integrals and signal heights characterizing (bio)molecules that are studied using high‐pressure NMR spectroscopy. So far, solvent compression has not been considered when quantitative high‐pressure NMR spectroscopy was used to characterize (bio)molecules.

7Li(15N,14C)8Be reaction and 13,14C + 8Be nuclei interactions

Ядерна фізика та енергетика, 2017
Angular distributions of the 7Li(15N,14C)8Be reaction were measured at the energy Elab(15N) = 81 MeV. The reaction data were analyzed within coupled-reaction-channels (CRC) method. The 7Li + 15N elastic and inelastic scattering and the more important one-

Quantification of total endogenous nitrogen losses in broilers using a minimally invasive 15N-isotope dilution method

Animal
Total endogenous nitrogen (N) losses (ENLs) measurement in broilers is important for quantifying dietary true N digestibility. Basal ENLs are commonly quantified using enzymatically hydrolysed casein (EHC) or EHC-ultrafiltration (EHC-UF), whereas diet ...

Optimal control of fast and high-fidelity quantum gates with electron and nuclear spins of a nitrogen-vacancy center in diamond

, 2015
A negatively charged nitrogen vacancy (NV) center in diamond has been recognized as a good solid-state qubit. A system consisting of the electronic spin of the NV center and hyperfine-coupled nitrogen and additionally nearby carbon nuclear spins can form

Linear and Two‐Dimensional Infrared Spectroscopy of the Multifunctional Vibrational Probe, 3‐(4‐Azidophenyl) Propiolonitrile. Deperturbing a Fermi Triad by Isotopic Substitution

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Linear infrared spectroscopy combined with isotope labeling and density functional theory unravels the origin of a Fermi triad in a multifunctional vibrational chromophore. Ultrafast 2DIR‐spectroscopy reports directly on the dynamics and the intramolecular vibrational energy flow pathways in the isotopically deperturbed system. Abstract Infrared probes

Accurate measurement of ^{13}C - ^{15}N distances with solid-state NMR

, 2006
Solid-state NMR technique for measureing distances between hetero-nuclei in static powder samples is described. It is based on a two-dimensional single-echo scheme enhanced with adiabatic cross-polarization. As an example, the results for intra-molecular

Detection of the GH Analogue Redalsomatropin Alfa in Sports Drug Testing: Immunological Approaches and LC‐HRMS/MS

Drug Testing and Analysis, EarlyView.
After evaluating the compatibility of the GH analogue redalsomatropin alfa with approved doping control immunoassays for rhGH, it was implemented into the existing detection method for somatrogon employing affinity purification with GHR‐Fc‐conjugated magnetic beads, tryptic digestion, and LC‐HRMS/MS to allow for a specific and sensitive detection ...
