Decay angular distributions of p[pi]- states formed in diffraction dissociation of neutrons on carbon
(Elsevier, 1972-08-01)
We present decay angular distributions of the p[pi]- system formed from the interactions of 25-30 GeV/c neutrons on a carbon target. The data are studied as afunction of t', which allows a partial separation of coherent ...
Multiple Compton scattering gamma ray imaging camera
(Elsevier, 1990-12-20)
With the recent advances in position sensing detectors, a compact, multiple layered, Compton scattering gamma ray imaging camera has been investigated for technological feasibility. Beginning from Kamea and Hanada's recent ...
A Flexible Spline Model of the Spin Echo with Applications to Estimation of the Spin-Spin Relaxation Time
(Elsevier, 1994-12)
Under weak mathematical assumptions, the distortion due to B0 inhomogeneity is shown to take the form of a characteristic function, which is the Fourier transform of a probability distribution, A model of the spin echo is ...
Diffraction dissociation of neutrons in the reaction dp --> ppp[pi]- at 25 GeV/c
(Elsevier, 1974-09-18)
We observe the reaction dp --> pspec (p[pi]-)p in a bubble chamber exposure at 25 GeV/c incident deuteron momentum. The (p[pi]-) system with invariant mass below 2.0 GeV is interpreted as neutron diffraction dissociation. ...
Recovery and purification of no-carrier-added [18F]fluoride with bistrimethylsilylsulfate (BTMSS)
(Elsevier, 1991)
No-carrier-added trimethylsilyl[18F]fluoride (TMS[18F]F) was rapidly liberated from a variety of dry supports containing unreactive [18F]fluoride by simply heating with neat bistrimethylsilylsulfate. The supports included ...
The performance of "Virtual Phase" CCDs as detectors of minimum-ionizing particles
(Elsevier, 1987-10-01)
The Texas Instruments "Virtual Phase" CCD has been the basis of an ambitious design for a precision vertex detector to be used at the Stanford Linear Collider. The performance of this chip shows promise for future use in ...
Photoluminescence studies of layered transition metal phosphorus chalcogenides and their pyridine intercalation compounds
(Elsevier, 1986-06)
Ultraviolet photoexcitation of Cd2P2S6 and Zn2P2S6 single crystals produces a characteristic photoluminescence between 2.5 and 1.5 eV. Mn2P2S6 exhibits only low energy emission due to transitions between localized d-orbital ...
The operation of a pressurized ultraviolet photoionization threshold cherenkov counter
(Elsevier, 1981-07-15)
We have successfully tested an ultraviolet photoionization Cherenkov counter in a 10 GeV/c pion beam. The counter has been tested to 11 atm pressure for use as a [pi]-K separator. The design and operation of the counter ...
Exact solution of the pairing problem in the LST scheme
(Elsevier, 1969-05-05)
Exact solutions for the pairing interaction problem in the LST scheme are formulated in terms of the matrix elements of pair creation and annihilation operators for pairs coupled to zero orbital angular momentum. General ...
Microcomputer control of radiochemical processes
(Elsevier, 1985-11)
A system for control of radiochemical processes has been designed and constructed. Control passes through a single 8-bit port (6522 VIA) to up to 64 on-off sensors and 64 on-off switches. The outputs are latched; they are ...
