The HIPSE (heavy-ion phase-space exploration) model, by Lacroix et al., has been used to examine nucleon transfer during the interaction of the projectile and target [1]. The results of the HIPSE model were compared to experimental data obtained on the FAUST array (Forward Array Using Silicon Technology) for F + Ag, F + Au, Na + Au, and Ne + Au at 32 MeV/u [2]. The apparent mass change of the p...

We have measured the scattering angle dependence of cross sections for ionization in p+H2 collisions for a fixed projectile energy loss. Depending on the projectile coherence, interference due to indistinguishable diffraction of the projectile from the two atomic centers was either present or absent in the data. This shows that, due to the fundamentals of quantum mechanics, the preparation of t...

BACKGROUND Vascular embolization of a projectile discharged from a weapon is a rare event. In this report a hunter's errant gunshot struck a farmer in the left chest. CASE REPORT The projectile was lodged between the apex of the heart and the diaphragm. The patient was treated non-operatively and was discharged home only to return to the emergency department with chest pain and subsequent ide...

A series of simulations were carried out to reproduce unsteady combustion around the hypervelocity cylindrical projectiles. A simplified two-step chemical reaction model was used to handle the reactions behind the bow shock. The simulations were examined with various parameters, such as projectile speed, initial pressure, and projectile diameter, and the unsteady mode of the Large-Disturbance r...

A method to efficiently generate a complete aerodynamic description for projectile flight dynamic modeling is described. At the core of the method is an unsteady, time accurate computational fluid dynamics simulation that is tightly coupled to a rigid body dynamics simulation. A set of n short time snippets of simulated projectile motion at m different Mach numbers is computed and employed as b...

In conventional nuclear experiments a beam of accelerated nuclei collides with a target nucleus that is surrounded by other nuclei in a molecule, or in condensed matter, or in plasma environment. It is shown that for low collision energies the nuclear reaction is strongly boosted by the environment. The effect originates from a chain of preliminary three elastic collisions which transform the p...

This study aims to investigate the penetration of a projectile into a surrogate human tissue numerically, using Finite Element (FE) simulation. 20% Balistic Gelatin material (BG) is simulated with an elasto-plastic hydrodynamic constitutive law, and then impacted by steel spheres at different velocities. The results from the FE simulations are compared with existing experimental data and other ...

Measurements of reaction cross sections are routinely used to deduce effective nuclear root mean square ~rms! radii by comparison with theoretical model predictions. Cross sections calculated using the optical limit Glauber model depend strongly on the rms radius of the density assumed for the projectile nucleus. We investigate such calculations by assuming a range of projectile density distrib...

In conventional nuclear experiments a beam of accelerated nuclei collides with a target nucleus that is surrounded by other nuclei in a molecule, in condensed matter, or in a plasma environment. It is shown that for low collision energies possible nuclear reactions (including deuterium fusion) are strongly boosted by the environment. The effect originates from a chain of preliminary three elast...
