12C(7Li, t)16O and stellar helium fusion
(Elsevier, 1978-07-31)
The reaction 12C(7Li, t)16O has been studied at E(7Li) = 34 MeV with the LASL tandem accelerator and QDDD magnetic spectrometer. Angular distributions to levels with Ex J[pi] = 1- levels, which are of great importance in ...
On the Asymptotic Stability of Reactors with Arbitrary Feedback
(The American Institute of Physics, 1970-01)
A theorem for the boundedness and asymptotic stability of a point reactor with an arbitrary feedback is stated and proved. The criteria obtained are shown to be essentially the same as those given by Akcasu and Dolfes. The ...
Dynamics of excimer laser‐ablated aluminum neutral atom plume measured by dye laser resonance absorption photography
(The American Institute of Physics, 1991-04-15)
We report the first dye laser resonance absorption photographs of a single species of aluminum ground‐state neutral atoms in the plume ablated from solid aluminum by KrF excimer laser radiation. Aluminum ground‐state neutral ...
On the Detectability of Star-Planet Interaction
(IOP Publishing, 2012)
Magnetic (or tidal) interactions between "hot Jupiters" and their host stars can potentially enhance chromospheric and coronal activity. An ideal test bed for investigating this effect is provided by the extreme WASP-18 ...
Optical properties and structure characterization of sapphire after Ni ion implantation and annealing
(The American Institute of Physics, 2005-10-01)
Implantation of 64 keV64keV Ni ions to sapphire was conducted at room temperature to 1×1017 ions/cm21×1017ions∕cm2 with a current density of 55 or 10 μA/cm210μA∕cm2. Metallic Ni nanoparticles were formed with the 5 μA/cm25μA∕cm2 ...
Computations of three‐dimensional Rayleigh–Taylor instability
(The American Institute of Physics, 1990-05)
The fully three‐dimensional deformation of an interface between two fluids resulting from a Rayleigh–Taylor instability is studied numerically in the limit of weak stratification. The Navier–Stokes equations are solved by ...
Surface corona-bar discharges for production of pre-ionizing UV light for pulsed high-pressure plasmas
(2010-12)
Multi-atmospheric pressure, pulsed electric discharge excited lasers require pre-ionization to produce spatially uniform glows. Many such systems use corona bars to produce ultraviolet (UV) and vacuum ultraviolet (VUV) ...
Theory of Oscillation of a Viscoelastic Medium between Parallel Planes
(The American Institute of Physics, 1959-12)
A theoretical description of sinusoidal oscillation of an incompressible viscoelastic medium between fixed infinite parallel planes is presented. The mechanical properties of the viscoelastic medium under sinusoidal shear ...
Self-assembled quantum dots: A study of strain energy and intersubband transitions
(The American Institute of Physics, 2002-11-15)
In this article we examine the strain energy and intersubband optical transitions in self-assembled dots on GaAs and InP substrates. On the GaAs substrate, in addition to the InAs/GaAs dots we examine strain compensated ...
Profiling and modeling of dc nitrogen microplasmas
(The American Institute of Physics, 2003-09-01)
This article explores electric current and field distributions in dc microplasmas, which have distinctive characteristics that are not evident at larger dimensions. These microplasmas, which are powered by coplanar thin-film ...
