On the 2Δp/n structure of PbPbOPb tunnel junctions

Physics Letters, 1966
The fine-structure of the tunneling characteristics observed [1] in PbPbOPb superconducting tunnel junctions has been interpreted as 2 Δp/n structure due to the breaking of p electron pairs and the tunneling of n electrons in the same processes.

Structure of liquid K-Pb alloys

Physica B+C, 1987
The structure factors of liquid Pb, Ko.zsPbo 75r KO 6sPbo 35 and Ko.80Pbo 2ohave been measured by means of neutron diffraction. The main peaks of the structure factorsof the alloys are preceded by a pre-peak which is most pronounced in Ko,50Pbo This prepeakindicates that there is considerable orderingin the alloys, although there is also evidencefor a ...

Electronic Structure of PbS, PbSe, and PbTe

physica status solidi (b), 1970
AbstractThe electronic band structures of PbS, PbSe, and PbTe have been calculated using the relativistic Green's function method. The choice of a relativistic atomic potential for Pb and of nonrelativistic atomic potentials for S, Se, and Te inthe muffin‐tin spheres results in similar band models for the lead salts.

The structure of Bacillus subtilis bacteriophage PBS 1

Journal of Ultrastructure Research, 1967
The structure of bacteriophage PBS 1 has been studied by electron microscopy using negative staining. Two unique structures were observed: several large helical tail fibers, and a number of “contraction fibers” seen only on contracted particles. The tail sheath was seen at several different stages of contraction. Approximate dimensions of the phage are

The crystal structure of the superconductor with Pb substitution

Journal of Physics: Condensed Matter, 1997
Pb-doped superconductors with x = 0.0 to 0.50 and increment steps of 0.1 have been synthesized. For x = 0.30, the sample has the highest superconducting transition temperature, (the zero-resistance temperature), and (the diamagnetic onset temperature) (results given by Shao H M, Lam C C, Fung P C W, Wu X S, Du J H, Shen G J, Chow J C L, Ho S L, Hung

LEED structure analysis of Pb(110)

Surface Science, 1990
Abstract The multilayer relaxation of Pb(110) was investigated by LEED. Data were taken at 130 and 300 K using a computer controlled video based technique. They were analyzed by full dynamical calculations. A quantitative comparison between experiment and theory via the Pendry R -factor confirms the strong contraction of the first layer spacing ...

Pb(II)-Carboxylate Structure and Reactivity: from Pb(II) Coordination Compounds to PbS Colloidal Nanocrystals

Inorganic Chemistry
Lead(II)-carboxylates are important precursors for preparing Pb-based semiconductor nanocrystals (NCs). However, the atomic structure of common Pb-carboxylate precursors (e.g., Pb-oleate) remains elusive. Here, we use a rigid yet soluble 4-tert-butylbenzoate (TBBA) as a model ligand to probe the binding and reactivity of Pb-carboxylates.

Study of electronic structure of liquid Pb

AIP Conference Proceedings, 2018
The Fiolhais et al.’s universal model potential in conjunction with the hard sphere technique of Percus and Yevick has been used for the study of electronic structure, Fermi energy and density of states of liquid Pb. The screening influence of the different forms of the local field correction functions proposed by Hartree (H) and Taylor (T) on the ...

Structure of liquid K-Pb alloys

Journal of Physics: Condensed Matter, 1989
he structure factors of liquid Pb, K0.25Pb0.75, K0.50Pb0.50, K0.65Pb0.35 and K0.80Pb0.20 have been measured by means of neutron diffraction. The main peaks of the structure factors of the alloys are preceded by a pre-peak which is most pronounced in K0.50Pb0.50.

STRUCTURE OF Pb-207 POPULATED IN Pb-208+Pb-208 DEEP-INELASTIC COLLISIONS

2015
The yrast structure of 207Pb above the 13=2+ isomeric state has been investigated in deep-inelastic collisions of 208Pb and 208Pb at ATLAS, Argonne National Laboratory. New and previously observed transitions were measured using the Gammasphere detector array.
