Collision Strengths for Excitation of Forbidden Lines [PDF]
Symposium - International Astronomical Union, 1968 New calculations of collision strengths are being made for ions in configurations npq, n = 2 and 3 and q = 1–5. Wave functions for the entire system are represented by sums over anti-symmetrized products of ion functions and orbitals for the colliding electron, and sets of coupled integro-differential equations are obtained for the colliding electron ...

Energies, 2022 Aiming at the problem that the current coefficient of restitution model cannot effectively predict energy dissipation in the multi-body system collision process, a coefficient of restitution model considering the yield strength is proposed in this ...

Research on MASS Collision Avoidance in Complex Waters Based on Deep Reinforcement Learning
Journal of Marine Science and Engineering, 2023 The research on decision-making models of ship collision avoidance is confronted with numerous challenges. These challenges encompass inadequate consideration of complex factors, including but not limited to open water scenarios, the absence of static ...

Polar molecule reactive collisions in quasi-1D systems
New Journal of Physics, 2015 We study polar molecule scattering in quasi-one-dimensional geometries. Elastic and reactive collision rates are computed as a function of collision energy and electric dipole moment for different confinement strengths.

Reaching supercritical field strengths with intense lasers
New Journal of Physics, 2019 It is conjectured that all perturbative approaches to quantum electrodynamics (QED) break down in the collision of a high-energy electron beam with an intense laser, when the laser fields are boosted to ‘supercritical’ strengths far greater than the ...

Various lithospheric deformation patterns derived from rheological contrasts between continental terranes: insights from 2-D numerical simulations [PDF]
Solid EarthContinents are formed by the amalgamation of numerous micro-terranes and island arcs, so they have spatially varying lithosphere strengths. The crème brûlée (CB) model and the jelly sandwich (JS) model have been commonly used to describe continental ...
