Lipid spin labeling and NMR study of interaction between polyadenylic acid: polyuridilic acid duplex and egg phosphatidylcholine liposomes. Evidence for involvement of surface groups of bilayer, phosphoryl groups and metal cations

Hydrophobic spin labeling of fatty acyl residues at 5-, 12- or 16-positions of phosphatidylcholine liposomes reveals the involvement of surface moieties of bilayer (up to fifth carbon atom of fatty acyl) into interaction with polyadenylic acid: polyuridilic acid duplex and magnesium ions.31P NMR spectra of this system demonstrate participation of nucleotide phosphoryl groups and metal cations in ternary complexation. © 1994 Springer

SPES4-pi:installation for exclusive study of nuclear reactions

EI SEP PHASE ACCThe paper describes the spectrometric system “SPES4–$\pi$” used at the National Laboratory Saturne (CE Saclay, France) for the exclusive study of the baryon resonance excitation in inelastic α and d scattering on the proton, as well as coherent pion production in charge exchange reactions. The system consists of the magnetic spectrometer SPES4 and two wide-aperture position-sensitive detector arrays, equipped with wire chambers and scintillator hodoscopes, installed around a large-gap C-shape dipole magnet
