Coherent Pion Photoproduction on Deuterium
Differential cross sections of the γd → dπ 0 reaction were measured at photon beam energies between 0.5 and 2.0 GeV over a wide angular range in the CM system. The experiment was performed in Hall B at Jefferson Lab using the CLAS detector. The excitation function, especially at backward CM scattering angles, has been studied with regard to effects due to intermediate on-shell η and ω rescatter...
متن کاملOn neutral pion electroproduction off deuterium
Threshold neutral pion electroproduction on the deuteron is studied in the framework of baryon chiral perturbation theory at next–to–leading order in the chiral expansion. To this order in small momenta, the amplitude is finite and a sum of two– and three–body interactions with no undetermined parameters. We calculate the S–wave multipoles for threshold production and the deuteron S–wave cross ...
متن کاملDeuterium Isotope Effects on the Silver
Solvent deuterium isotope effects support the view that the p-N02 and p-Me derivatives of benzaldehyde S.S-diethylacetal undergo silver ion-promoted hydrolysis in water by different mechanisms. scheme common [3] for O.O-acetals in the presence of H30 + ions, while for the latter we suggested a bimolecular A2-type mechanism with one (or more) water molecules in the slow phase of step (3). The co...
متن کاملPionic deuterium
The strong-interaction shift πD 1s and broadening Γ πD 1s in pionic deuterium have been determined in a high statistics study of the πD(3p-1s) X-ray transition using a high-resolution crystal spectrometer. The pionic deuterium shift will provide constraints for the pion-nucleon isospin scattering lengths extracted from measurements of shift and broadening in pionic hydrogen. The hadronic broade...
متن کاملEffects of Deuterium on Chlamydomonas reinhardtii
In order to develop software tools to monitor rates of total protein turnover in plants, attempts were made to maximally label all the proteins in vivo. Our study focused on the use of the stable isotope of hydrogen, deuterium, to label proteins of C. reinhardtii. The goal of this study was to determine the effect of the label on algal growth. C. reinhardtii is a unicellular green algae that is...
