We present the results of experiments studying the shape of craters formed by the normal impact of a solid spherical projectile into a deep noncohesive granular bed at low energies. The resultant impact crater surfaces are accurately digitized using laser profilometry, allowing for the detailed investigation of the crater shape. We find that these impact craters are very nearly hyperbolic in pr...

We study the multiple ionization and fragmentation of CO in collisions with slow He ions. Correlated measurements of all fragment ions and the projectile final charge state were performed using our coincidence COLTRIMS imaging technique coupled to projectile charge state separation. Complete fragmentations of CO, following double electron capture, into C+O with a total charge of 4 were investig...

A comparison of experimental heavy residue cross sections from the reactions 86Kr+64Ni,112,124Sn with the model of deep-inelastic transfer ( DIT ) is carried out. A modified expression for nucleon transfer probabilities is used at non-overlapping projectile-target configurations, introducing a dependence on isospin asymmetry at the nuclear periphery. The experimental yields of neutron-rich nucl...

The XM395 Precision Guided Mortar Munition (PGMM) is a fin-stabilized, laser-guided projectile (Fig. 1) that was being developed for the US Army’s 120mm Mortar System. The combination of its precision capability and high-explosive warhead made it very effective against its required target set, personnel protected by masonry walls, bunkers and lightly armored vehicles. During the PGMM developmen...

We have measured production yields and longitudinal momentum distributions of projectile-like fragments in the reaction 129 Xe + 27 Al at an energy of E lab =790 A·MeV. Production cross sections higher than expected from sys-tematics were observed for nuclei in the neutron-deficient tails of the isotopic distributions. A comparison with previously measured data from the fragmentation of 136 Xe ...

First evidence of photon emission from individual impacts of massive gold projectiles on solids for a number of projectile-target combinations is reported. Photon emission from individual impacts of massive Au(n) (+q) (1 ≤ n ≤ 400; q = 1-4) projectiles with impact energies in the range of 28-136 keV occurs in less than 10 ns after the projectile impact. Experimental observations show an increas...

INTRODUCTION There are numerous cases of abdominal injuries due to bullets. Abdominal injuries due to bullets are a diagnostic and therapeutic challenge. Here, an unusual case of an abdominal perforation caused by a metal projectile, lead to confusion in the interpretation of the preoperative computer tomography. CASE PRESENTATION We present an unusual case of a 32-year-old male worker who su...

We discuss intermediate-energy single-nucleon removal reactions from deformed projectile nuclei. The removed nucleon is assumed to originate from a given Nilsson model single-particle state and the inclusive cross sections, to all rotational states of the residual nucleus, are calculated. We investigate the sensitivity of both the stripping cross sections and their momentum distributions to the...

Recent experiments at Fermilab and CERN have observed a strong asymmetry between the hadroproduction cross sections of leading D mesons, containing projectile valence quarks, and nonleading charmed mesons, without projectile valence quarks. The observed correlations of the πN → DX cross section with the projectile charge violates the usual assumption that heavy quark jet fragmentation factorize...

In this paper, trajectory prediction and control design for a desired hit point of a projectile is studied. Projectiles are subject to environment noise such as wind effect and measurement noise. In addition, mathematical models of projectiles contain a large number of important states that should be taken into account for having a realistic prediction. Furthermore, dynamics of projectiles cont...
