Search for pre-existing Delta states at BLAST from ²H(e,e'[Delta]⁺⁺
… potential. The pion production region has a resonant structure and is a promising location to search for pre-existing delta particles in deuterium. While, theoretical calculations predict that delta resonant states account for anywhere from 0.25 to 3.60% of the nuclear wave function, more …

Analyticity properties of the Jost function for spheroidal potentials
… the Jost function and the formation of bound and resonant states is then established for spheroidal potentials. The domain of analyticity of the spheroidal Jost function is studied for three classes of basis functions: those belonging to spherical potentials having only a bounded first and second …

Backward resonance production in pi minus plus proton goes to neutron pi plus pi minus at 8 GeV/c
… by backward production of the final states npo, nfo, and delta-(1232)pi+. Differential cross sections and decay angular distributions for these resonant states are presented and the implications for the production mechanisms discussed.

A study of nucleon unstable states produced in direct nuclear reactions
We study excited states of a nucleus that are unstable against nucleon decay. An expression is derived for the wave function of such an excited nucleus, using the continuum shell-model theory. The bound and resonant states of the shell-model Hamiltonian are treated on an equal footing. The resonant …

Photoionization of excited states of atomic hydrogen in a strong electric field
The photoionization of excited states of atomic hydrogen in a strong external electric field is examined theoretically and experimentally. A theoretical treatment which predicts novel effects in the excitation of the broad resonant states in the continuum from pure parabolic Stark states is …

Electron tunneling study of superconductors doped with magnetic atoms and nonmagnetic resonant state atoms: Indium-chromium, zinc-manganese, and aluminum-manganese
… measurements to determine the density of states of quench-condensed thin films of In-Cr, Zn-Mn, and Al-Mn, and of annealed thin films of Zn-Mn. The results on In-Cr and Zn-Mn were compared with Shiba's theory for magnetic atoms in superconductors. We observed the localized band of states …

Dicke enhanced energy transfer via off resonant coupling y Christopher Black.
… for second-order (indirect) coupling through off-resonant states. Specifically, the model hosts a second-order transfer of energy between two collections of two level systems via an off-resonant oscillator. No first-order transfer of energy is possible because the systems are optically isolated. …

Geometry, topology and mechanics of twisted elastic fibers
… batteries contains special topologically resonant states for which energy release is superslow. Finally, we apply our topological model to surgical knots. Through numerical simulation, we show that topology can be used to identify mechanically stable and balanced suture knots.

Quasinormal Modes of Nearly Extremal Black Holes
… these objects and the idea of co-modes or dual resonant states: solutions to the adjoint problem which can make identifying the frequencies easier. Finally, we shall use this framework and Gohberg-Sigal theory to prove existence results for zero-damped modes: firstly in the case of wave …

Nanostructures and alloys : multiple scattering and nonlinearities in phonon transport
… the coupling and the number of impurities. These resonant states become significantly coupled in silicon germanium alloys of concentrations over ten percent. Scattering rates, angle dependent scattering amplitudes, and local density of states calculations are subsequently performed for …

First experimental evidence of the Giant Pairing Vibration in atomic nuclei
… of the ground plus several known bound and resonant states of the residual nuclei are observed. In addition, two unknown broad structures are observed in the higher part of the excitation energy spectra, namely at 16.9 (FWHM = 1.2 MeV) in the 14C spectrum and at 13.7 MeV (FWHM = 2.5 MeV) in …
