Structure of 11Li in the cluster-orbital shell model for the 9Li + n + n system
(Elsevier, 1990-05-28)
The properties of 11Li are studied in detail in the cluster-orbital shell model assuming the structure of 9Li + n + n. The interactions acting between the constituent particles are carefully determined consistently with ...
Impact parameter study of high energy elastic scattering
(Elsevier, 1974-03-04)
The imaginary part of the proton-proton elastic scattering amplitude, as measured at the ISR, is examined in impact parameter. The transformed amplitude has two important properties. First, it is very accurately Gaussian ...
Laboratory angular distributions for the production of charged secondaries in inelastic proton-proton collisions at 102 GeV/c
(Elsevier, 1974-10-11)
Lab angular distributions for the production of charged secondary particles in inelastic proton-proton collisions are presented. Data are separately displayed for protons and for positive and negative mesons (pions and ...
Synthesis of a high specific activity 125I-labeled analog of PK 11195, potential agent for SPECT imaging of the peripheral benzodiazepine binding site
(Elsevier, 1989)
The peripheral benzodiazepine binding site ligand PK 11195 has been 125I-labeled by direct displacement of aromatic chlorine under solid-state conditions in 50-76% radiochemical yield and >94% radiochemical purity. ...
Proposed new reactor-activated positron source for intense slow e+ beam production
(Elsevier, 1988-03-01)
A novel method is suggested for producing a new positron (e+) emitting isotope in a nuclear reactor with application to slow e+ beams. The initial radiated sample is 124Xe which is transformed to 126I by two neutron ...
Impact of variations in physical parameters on glow curves for planchet heating of TL dosimeters
(Elsevier, 1994-12-30)
This study consists of a theoretical analysis of the directional planchet heating of Thermoluminescent Dosimeters (TLD) with an emphasis on influence of radiation field type, TL material properties, and heating scheme ...
An amplifier-discriminator module for very high energy [gamma]-ray astronomy
(Elsevier, 1990-07-15)
An eight-channel amplifier-discriminator module has been developed for processing fast photomultiplier signals from a ground-based [gamma]-ray imaging telescope. The module provides several outputs for recording pulse ...
Retractable carbon fibre targets for measuring beam profiles at the SLC collision point
(Elsevier, 1989-06-15)
Retractable targets of carbon fibres with nominal diameters of 30, 7 and 4.5 [mu]m have been in use at the collision point of the SLC (the SLAC Linear Collider). The target mechanism is compatible with the Mark II detector ...
Observations on horizontal symmetries and flavor changing neutral currents
(Elsevier, 1982-04-26)
We present a detailed study of the possibility of having a horizontal gauge symmetry, in addition to SU(3)c x SU(2)L x U(1). Grand unification is not used as a constraint. We concentrate on the horizontal group SU(3)H. ...
Gamma-gamma directional correlations in 140Ce
(Elsevier, 1971-11-29)
Directional correlation measurements have been performed on six [gamma]-ray pairs occurring in the de-excitation of 140Ce. Of these, two are 1-3 correlations with an unobserved intermediate [gamma]-ray. Both NaI(T1)-Ge(Li) ...
