Coulomb displacement energies in the shell
(Elsevier, 1968-06-24)
The experimental Coulomb displacement energies in the shell (except one) can be described by Hecht's Coulomb energy equation with a standard deviation of 8.5 keV if it is assumed that the Coulomb interaction radius is ...
Extended detectors in neutron time-of-flight diffraction experiments
(Elsevier, 1967-01-03)
[mu]-e conversion in nuclei and Z' physics
(Elsevier, 1993-11-22)
Together with the existence of new neutral gauge bosons, models based on extended gauge groups (rank > 4) often predict also new charged fermions. A mixing of the known fermions with new states with exotic weak-isospin ...
Irreducible diagrams in Landau-Ginzburg field theory
(Elsevier, 1981-10-19)
It is shown that the free energy W of a Landau-Ginzburg-Wilson field theory with O(n) symmetry may be written in terms of the generating function V of diagrams irreducible in both propagator and interaction lines. This ...
A mechanical time-of-flight neutron diffractometer
(Elsevier, 1974-02-01)
A mechanical time-of-flight (TOF) neutron diffractometer has been constructed and a system of data analysis developed for the study of noncrystalline substances through radial density functions. Measurements to wave vector ...
Shell-model calculation in 24Mg
(Elsevier, 1967-03-06)
A shell-model calculation is performed for 24Mg assuming wave functions with maximum symmetry in the spacial coordinates. Several interactions have been used including the Kallio-Kolltveit hard-core potential. A reasonable ...
A captive solvent method for rapid radiosynthesis: Application to the synthesis of [1-11C]palmitic acid
(Elsevier, 1985-08)
A method is described for the synthesis of [1-11C]palmitic acid,in which 11CO2 is reacted with a Grignard reagent trapped within the pores of microporous polypropylene powder in a column. The free acid is liberated by ...
Aqueous carbonic acid: A readily removable electrolyte for the recovery of [18F]fluoride from anion exchange resins
(Elsevier, 1991)
[18F]Fluoride was recovered from [18O]target water in high yield by trapping it on a microcolumn of an anion exchange resin (20 mg Dowex 1 x 8, 400 mesh) and subsequent elution of the column (in the reverse direction) ...
Comparison of methods for incorporating a radioiodinated residualizing cholesteryl ester analog into low density lipoprotein
(Elsevier, 1992-10)
Two different methods were evaluated for incorporating [125I]cholesteryl iopanoate ([125I]CI), a non-hydrolyzable cholesteryl ester analog, into LDL. The first procedure was an organic solvent delipidation-reconstitution ...
Experimental determination of transformation enthalpies of metastable phase transitions in ion-irradiated NiAl3
(Elsevier, 1991-07-01)
A novel experimental technique has been developed by which metastable phase transformations in thin films may be investigated. The technique is demonstrated by the determination of the enthalpies of transformation of two ...
