Despite its centennial exploration history, there are still unresolved questions about Meteor Crater, the first recognized impact crater on Earth. This theoretical study addresses some of these questions by comparing model results with field and laboratory studies of Meteor Crater. Our results indicate that Meteor Crater was formed by a high-velocity impact of a fragmented ...
The Navy Clothing and Textile Research Unit has developed two, experimental, Buoyant, Anti-Fragment, Bulletproof Vests which provide low-velocity protection against mortar shell bursts and secondary fragments (spall), provide protection against 30-caliber...
Spin polarization of43Ti produced through the projectile fragmentation process in46Ti on C collisions at 116 MeV/nucleon has been observed as a function of fragment momentum by means of beta-decay asymmetry. From the momentum dependence of the fragment polarization, it was concluded that negative angle deflection ...
Neutron rich isomers near {sup 68}Ni have been investigated via deep-inelastic collisions as a function of projectile mass and incident energy. Gamma-rays from the ns- {mu}s isomers were measured in coincidence with projectile-like fragments. Yields of 26 isomers have been derived from three experiments with different ...
A large-solid-angle array has been used to determine the multiplicity of Z = 1 and Z = 2 particles accompanying projectile breakup into two fragments each with 5 less than or equal to Z less than or equal to 8. The charge balance obtained shows that projectile breakup is not associated with an unusual charge transfer to the target. 13 ...
A theoretical and experimental model of the protective effect of thin plates against slow projectiles or fragments was designed, for practical application in the field of accident and catastrophe prevention. The minimum thickness needed in a plate compose...
The projectile-fragment separator FRS, recently installed at the heavy-ion synchrotron SIS18 at GSI, was used to measure the formation cross sections and longitudinal-momentum distributions of fragments produced by removing one, two or three protons from ...
An experimental investigation has been undertaken to study the fragmentation of soft and hard rock under conditions of impact by spherical steel projectiles and standard ammunition. Laboratory tests involving the firing of a 1/4-inch-diameter steel sphere...
