Determination of Recoil-Free Fractions From 151Eu Mossbauer Spectra of EuBO3
… is a result of a nuclear transition from one energy level to another. If the emitting nucleus is not bound in a crystal lattice, some of the transition energy, or the difference in energy of the two nuclear levels, may be imparted to the nucleus as it recoils, much as a gun acquires energy in …

Photsluminescence of ZnO: Radioactive ion-implantation and transition metal defects
… to be a damage related band, created by the high recoil energy of the 72ge daughter product. Radioactive isotopes of Cu and Ni, with Cu as a decay product, were implanted into single-crystal ZnO in order to investigate the relationship between Cu and the structured green band, a common feature …

An investigation of the ergonomics and biomechanics of rifle shooting from the standing position
… forces in the vertical and horizontal plane, recoil force on the shoulder and the grip force of the trigger hand. Kinematic data was collected with a video camera. The study revealed that recoil energy was dependent on the attributes of the shooter. Handgrip forces were found to be well below …

Automating radiation damage studies of materials irradiated by high-energy protons using multiphysics simulations
… thicknesses and bombards them with high-energy proton beams. The slabs are automatically sorted, a meshed geometry is created, and the recoil energy information is entered into a multiphysics Finite- Element solver. Ultimately, the optimal beam current for which the temperature gradient …

The design and construction of a constant acceleration drive system for Mössbauer experiments
… a gamma ray. The nucleus, if free to do so, will recoil and take some of the transition energy as recoil energy leaving less energy for the emitted gamma ray. This gamma ray does not have enough energy to excite a similar nucleus and will, therefore, not by resonantly absorbed due to the fact that …

Molecular dynamic simulation of xenon bubble re-solution in uranium dioxide
… (MC) simulations are used to obtain the full recoil energy spectrum of fission gas atoms, and MD simulations are used to build an extensive library of fission gas atom re-solution events. This library is used for calculating a recoil spectrum averaged displacement distribution of fission gas …

The search for dark matter in xenon: Innovative calibration strategies and novel search channels
… 212Pb beta emission can be used for low-energy electronic recoil calibration in searches for dark matter. The isotope spreads throughout the entire active region of the detector, and its activity naturally decays below background level within a week after the source is closed. I find no …

Trapped hydrogen vibrational density of states measurement using IINS PdH0.0011 at 5 K and 300 K with incident neutron energy of 250 meV
… scattering (IINS) at two temperatures over the energy transfer range of 250 meV. The primary objective of this study was to study the vibrational density of states (VDOS) of deformed PdH0.0011 at 5 and 300 K over an energy transfer range corresponding to the multi-phonon and second order …

A Cavity-stabilized diode laser for dipole trapping of ytterbium
… standing wave has high enough intensity that the recoil energy of the gain transition is smaller than the energy spacing between motional modes of the trapped atoms. This situation is known as the Lamb-Dicke regime and means that there is an absence of recoil broadening. The large spacing between …

Intermediate energy proton irradiation: An experimental and analytical foundation for bulk radiation damage testing
… will need to survive heavy exposure to high energy neutrons, outside of our current operating experience with fission reactors. Understanding the evolution of mechanical properties during radiation damage is essential to the design and commercial deployment of these systems. However, existing …
