Extension of the Chou-Yang model to multiparticle processes
(Elsevier, 1975-04-21)
A natural and essentially unique extension of the Chou-Yang model to multiparticle processes is presented. The multiparticle amplitudes are derived from the physical ideas of the original Chou-Yang approach. The beam and ...
Laminar free-surface flow into a vertical cylinder
(Elsevier, 1975-03)
This study concerns the unsteady free-surface flow of a Newtonian fluid issuing vertically upwards from a tube in the base of a vertical cylindrical cavity. Experimental and numerical results are presented and discussed.The ...
On the aerodynamic heating of an oscillating surface
(Elsevier, 1975)
The energy equation for the laminar flow of an incompressible, viscous fluid induced by the axial oscillation of an infinite flat plate is solved by the Laplace transformation technique. Temperature oscillations of the ...
On the application of group theory to molecular excitons
(Elsevier, 1975-08)
In this paper a group theoretical approach was employed for the classification and construction of molecular exciton wavefunctions for two important crystal structures (naphthalene--anthracene and benzene), utilizing the ...
Experimental studies of the electrical conductivity and phase transition in Fe3O4
(The American Institute of Physics, 1975-04)
Above the Verwey transition the conduction electrons in Fe3O4 are described best by a band model. Those experimental data interpreted as indicating localized hopping conduction are either not susceptible to definitive ...
Observation of structure in elastic pp scattering at 100 and 200 GeV/c
(Elsevier, 1975-10-27)
The elastic differential cross section for pp scattering has been measured up to a momentum transfer of ||t|| = 3(GeV/c)2 at 100 GeV/c and 200 GeV/c incident momenta. The 200 GeV/c measurements shows a diffractive like dip ...
Spray cooling of air-cooled compact heat exchangers
(Elsevier, 1975-02)
This paper investigates the technical feasibility of air-cooled compact heat exchangers with liquid-droplet spray in a fine mist as a more effective heat rejection system between a condensing vapor or hot fluid system and ...
Mixed‐crystal infrared studies on melt‐crystallized polyethylene
(The American Institute of Physics, 1975-10)
In order to minimize the occurrence of heterogeneities, or segregation, of polyethylene and poly(ethylene‐d4) in mixed‐crystal systems during melt crystallization, it has been found that conditions of high molar ratio of ...
Backflow and density excitations in quantum fluids
(Kluwer Academic Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1975-01)
By the use of the f sum rule and a separation of density excitations into single and multiple excitations, we derive exact quantum expressions for the backflow contribution to the dynamic structure function S ( k , Ω) and ...
