ELASTIC SCATTERING AT RELATIVISTIC ENERGIES OF ALPHA PARTICLES AND PIONS BY NUCLEI USING AN OPTICAL POTENTIAL
… lower energies. This code was used to analyze alpha particle and pion scattering at relativistic energies upon different target nuclei and to find a relativistic potential for a system at a given energy. The target particles in the alpha study were 12C, 40,42,44,48Ca and other alphas. The pions …

LOCO-REGIONALLY TARGETING INTERLEUKIN-13 RECEPTOR ALPHA-2 AND MAXIMIZING THERAPEUTIC ACCESS TO GLIOBLASTOMAS USING BIOMARKER DIRECTED ALPHA PARTICLES
… delivering therapies. Interleukin-13 receptor alpha-2 (IL13RA2) is one such GBM restricted biomarker which was previously discovered to be highly upregulated in about 75% of GBM samples and found to be an effective target for delivering tumor-specific cytotoxic therapeutics (Debinski et al, …

An Alpha Loss-Cone Instability in the Central Cell of a Tandem Mirror Reactor
D-T fusion-born alpha particles are mirror-confined in the central cell of a tandem mirror reactor. The resulting anisotropic loss-cone distribution of the alpha particles in velocity space is capable of destabilizing low frequency plasma waves, thus affecting the energy balance in a tandem mirror …

Theory of Alpha-Nucleus Collisions at High Energies
<p>The interaction of high energy alpha particles with atomic nuclei is considered using multiple scattering theories. Semi-classical solutions to coupled-channel equations derived from Watson's form of the nucleus-nucleus multiple scattering series are shown to be equivalent to the Glauber …

Alpha decay and alpha elastic scattering by heavy nuclei
… Merchant and Perez to successfully describe alpha decay half lives for more than 400 nuclei. An important feature of this model is that it envisages preformed (preformation factor, P=1.0) alpha particles in the parent nuclei to be moving in orbits with a large value of a global quantum …

A Multi-Region Multi-Timescale Burning Plasma Dynamics Model for Tokamaks
… The deuterium-tritium fusion generates energetic alpha particles, which first transfer their energy to core electrons. The heated electrons and remaining fusion alpha particles then heat core ions through Coulomb collisions, which can increase the fusion reaction rate and may conceivably lead to a …

Methods for studying single ionizing particles
… decades has the reality of atoms and sub-atomic particles been established beyond doubt. Final proof of their existence has come with the ability to deal with oertain individual particles, whioh can be recognized by possession of some special property. Of the methods at present available, the …

Ionization Chamber Design, Development, and Testing for the UNM Fission Fragment Spectrometer
… energy resolution of 1.5% at high pressures for alpha particles has been measured. In addition to energy measurements, the ionization chamber has achieved measuring the range of alpha particles and both light and heavy fission fragments through use of an active cathode. Further characterizing has …

LET dependence of radiation-induced bystander effects using human prostate tumor cells
… cell culture dishes for irradiation with alpha particles (average energy 3.14 MeV) from a 241Am source, or in 6-well plates for irradiation with 250 kVp x-rays at 25°C. In parallel experiments, the tumor cells were incubated at 4°C for one hour prior to irradiation and irradiated on ice to …

Alpha emission from the interactions of 14-200 MeV neutrons on carbon-12
Cross-sections for the production of alpha particles from the ¹²C(n,α)⁹Begs and ¹²C(n,n')3α reactions were measured for incident neutrons in the energy range 25 to 52 MeV. The measurements were reduced to absolute cross-sections by simultaneously observing deuteron recoils from n-d elastic …

Dynamical equilibrium and stability of a D-T fueled fusion reactor
… was employed in the reactor to remove ions, alpha particles, and impurities. Equilibrium point solutions and fractional burn-ups were obtained after simulating different operating regimes of a D-T fueled fusion reactor. This was done essentially by varying a temperature dependent confinement …

Point defect engineering in germanium
… To this end, we have used radiation (gamma rays, alpha particles, and neutrons) to controllably introduce point defects in crystalline germanium, which were then characterized by Deep-Level Transient Spectroscopy (DLTS), a technique that allows the determination of the activation energy, capture …
