Symmetry tests with highly charged ions
(Elsevier, 1989-09-02)
We summarize the present status of testing the standard model of parity nonconservation in neutral atoms, emphasizing the success in understanding the semileptonic weak interactions. There is good agreement for the nuclear ...
A threshold gas Cerenkov counter for a 200 GeV/c beam
(Elsevier, 1971-07-15)
A test of a prototype gas Cerenkov counter is described. The emphasis was on testing various photomultipliers with extended quantum efficiency in the ultraviolet.
The (3He, n) reaction in the lower 2s1d shell
(Elsevier, 1975-12-22)
The two-proton transfer reaction (3He, n) has been measured on four gas targets, 16O, 18O, 20Ne, and 22Ne, with an incident 3He energy of 18.3 MeV. The data were taken with a neutron time-of-flight spectrometer in the ...
Fractal energy transport: Random walk simulations on long-range percolation clusters
(Elsevier, 1984-12)
Luminescene from naphthalene alloys is quenched by long-range exciton hops. These are modeled by long-range random walks on long-range percolation clusters with a range-dependent hopping time. Both linear and exponential ...
Coulomb displacement energies of the T = 1, J = 0 states of A = 42 nuclei
(Elsevier, 1978-07-24)
Coulomb displacement energies of the T = 1, J = 0+ and 61+ states of A = 42 nuclei are analyzed with previously known charge dependent forces and effects, and with the available HartreeFock single-particle wave functions. ...
Pituitary localization of 3H-spiroperidol by an Uptake/Storage Mechanism?
(Elsevier, 1986)
The lack of a pituitary imaging agent combined with the considerable clinical value for such an agent prompted an examination of 3H-spiroperidol (3HSp). Spiroperidol was selected for initial evaluation based on its high ...
Investigation of [epsilon]1 and the 3PJ phase shifts in the n-p system by the measurement of polarization transfer coefficients in p-d elastic scattering
(Elsevier, 2006-05-10)
The 3S1-3D1 mixing parameter [epsilon]1 and the 3PJ phase shifts in the N-N system at low energy are investigated in the three nucleon system. The sensitivity of polarization transfer coefficients in p-d elastic scattering ...
Bismuth germanate scintillator as a fast high-energy ion detector
(Elsevier, 1984-08-01)
The pulse-height response and timing characteristics of bismuth germanate scintillator haven been determined for light and heavy ions (A [les] 35 E [les] 250 MeV). Timing resolutions of [les] 250 ps have been observed.
Improvements in the CR39 polymer for the macro experiment at the Gran Sasso Laboratory
(Elsevier, 1991)
We discuss the preparation of different samples of the CR39 polymer and a number of tests performed with high energy heavy ions. The quality and reproducibility of the manufactured CR39 is discussed as well as the implications ...
Synthesis of 11C-labelled thymidine for tumor visualization using positron emission tomography
(Elsevier, 1989)
A no-carrier added synthesis of [11C]thymidine from cyclotron produced [11C]methyl iodide is presented. The bis-silylated derivative of the lithium salt of 5-bromo-2'-deoxyuridine is treated with [11C]methyl iodide in THF ...
