چکیده
We compute the radiative ro-vibrational emission spectrum of H2 involving quasibound states via a simple numerical method resolution Schr\"odinger equation by introducing modifed effective molecular potential. The comparison eigenvalues obtained with our approximation and other theoretical methods based on scattering resonance properties is excellent. Electric quadrupole magnetic dipole contributions are calculated we confirm previous computations Forrey electric transition Einstein coeffcients. astrophysical relevance such levels emphasized

A scheme over quasi-prime spectrum of modules
The notions of quasi-prime submodules and developed Zariski topology was introduced by the present authors in cite{ah10}. In this paper we use these notions to define a scheme. For an $R$-module $M$, let $X:={Qin qSpec(M) mid (Q:_R M)inSpec(R)}$. It is proved that $(X, mathcal{O}_X)$ is a locally ringed space. We study the morphism of locally ringed spaces induced by $R$-homomorphism $Mrightar...
متن کاملη–Helium Quasi-Bound States
The cross section and tensor analysing power t20 of the ~ d d → He η reaction have been measured at six c.m. momenta, 10 ≤ pη ≤ 90 MeV/c. The threshold value of t20 is consistent with 1/ √ 2, which follows from parity conservation and Bose symmetry. The much slower momentum variation observed for the reaction amplitude, as compared to that for the analogous p d → He η case, suggests strongly th...
متن کاملPolarization-bound quasi-continuum states are responsible for the "blue tail" in the optical absorption spectrum of the aqueous electron.
The electronic absorption spectrum of the aqueous electron in bulk water has been simulated using long-range-corrected time-dependent density functional theory as well as mixed quantum/classical molecular dynamics based on a one-electron model in which electron-water polarization is treated self-consistently. Both methodologies suggest that the high-energy Lorentzian tail that is observed exper...
متن کاملOverview of K̄-Nuclear Quasi-Bound States
The K̄-nucleus interaction near threshold is strongly attractive and absorptive as suggested by fits to the strong-interaction shifts and widths of K−-atom levels [1]. Global fits yield ‘deep’ optical potentials with Re VK̄(ρ0) ∼ −(150 − 200) MeV [2–5], whereas more theoretically inclined studies that fit the low-energy K−p reaction data, including the I = 0 quasi-bound state Λ(1405) as input for...
متن کاملBound state spectrum in the finite volume
The signature of bound state formation on the lattice is of particular interest in this talk. In the finite volume, where all states have discrete energies, it is rather hard to distinguish between a bound state and a scattering state if the bound state were close to threshold, i.e. like a “loosely bound state”. To study bound states in the finite volume, we calculate the positronium spectrosco...
