  2. Electron nuclear double resonance - Wikipedia

    Electron nuclear double resonance (ENDOR) is a magnetic resonance technique for elucidating the molecular and electronic structure of paramagnetic species. [1]

  3. Path integral formulation - Wikipedia

    en.wikipedia.org/wiki/Path_integral_formulation

    The path integral formulation is a description in quantum mechanics that generalizes the stationary action principle of classical mechanics.It replaces the classical notion of a single, unique classical trajectory for a system with a sum, or functional integral, over an infinity of quantum-mechanically possible trajectories to compute a quantum amplitude.

    Achilles' sacrifice of Trojan prisoners, 4th-century BC fresco from Vulci.The eidolon of Patroclus is second from left.. In ancient Greek literature, an eidolon (/ aɪ ˈ d oʊ l ɒ n /; [1] Ancient Greek: εἴδωλον 'image, idol, double, apparition, phantom, ghost'; plural: eidola or eidolons) is a spirit-image of a living or dead person; a shade or phantom look-alike of the human form.

    Thus, the lifetime of a particle is the direct inverse of the particle's resonance width. For example, the charged pion has the second-longest lifetime of any meson, at 2.6033 × 10 −8 s. [2] Therefore, its resonance width is very small, about 2.528 × 10 −8 eV or about 6.11 MHz. Pions are generally not considered as "resonances".

  6. Magnetic resonance (quantum mechanics) - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance...

    The Rabi frequency should not be confused with the field's own frequency. Since many atomic nuclei species can behave as a magnetic dipole, this resonance technique is the basis of nuclear magnetic resonance, including nuclear magnetic resonance imaging and nuclear magnetic resonance spectroscopy.

  7. Electron paramagnetic resonance - Wikipedia

    en.wikipedia.org/.../Electron_paramagnetic_resonance

    Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a method for studying materials that have unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but the spins excited are those of the electrons instead of the atomic nuclei. EPR spectroscopy is particularly ...

  9. High-availability Seamless Redundancy - Wikipedia

    en.wikipedia.org/wiki/High-availability_Seamless...

    An HSR network node (DANH) has at least two Ethernet ports, each attached to a neighbour HSR node, so that always two paths exist between two nodes. Therefore, as long as one path is operational, the destination application always receives one frame. HSR nodes check the redundancy continuously to detect lurking failures.
