Kinetic Energy Release in Metastable Transitions. I
A method is described for detecting metastable transitions which take place with the release of kinetic energy in the field-free region between the source and electrostatic analyser of a doublefocusing mass spectrometer, and a procedure is given for evaluating the kinetic energy release. Values are given for a number of transitions and are in agreement with those obtained by other methods where...
متن کاملDEVELOPMENT OF A TUNGSTEN HEAVY ALLOY, W-Ni-Mn, USED AS KINETIC ENERGY PENETRATOR
Abstract: The objective of this research was to develop a tungsten heavy alloy (WHA) having a microstructure and properties good enough to penetrate hard rolled steels as deep as possible. In addition this alloy should not have environmental problems as depleted uranium (DU) materials. For this purpose a wide spread literature survey was performed and on the base of information obtained in ...
متن کاملTesting the kinetic energy functional : Kinetic energy density as a density functional
A new method for defining an energy density for the noninteracting kinetic energy of density functional theory is given. The resulting energy density is a density functional determined completely by the kinetic energy functional itself. Although this method is not constructive, it allows for a direct comparison between exact and approximate functionals pointwise in space. For simple systems, th...
متن کاملThe Kinetic Sunyaev-zel’dovitch Effect as a Dark Energy Probe
Upcoming observatories will be able to detect the kinetic Sunyaev-Zel’dovitch (kSZ) effect with unprecendented signal-to-noise, and cross-correlations with foreground signals such as galaxy counts are a promising way to extract additional cosmological information. We consider how well a tomographic galaxy-count cross-correlation experiment, using data from WMAP, ACT and SALT, can significantly ...
متن کاملVortex stretching as a mechanism for quantum kinetic energy decay.
A pair of perturbed antiparallel quantum vortices, simulated using the three-dimensional Gross-Pitaevskii equations, is shown to be unstable to vortex stretching. This results in kinetic energy K(∇ψ) being converted into interaction energy E(I) and eventually local kinetic energy depletion that is similar to energy decay in a classical fluid, even though the governing equations are Hamiltonian ...
