Scattering incoming states

The full scattering incoming states E, n ) are eigenstates of the Schrodinger equation... [Pg.111]

The above results deal with photodissociation. A similar formulation can be applied to an inelastic scattering event, for example, the scattering of A + BC from an initial state E, m 0) into a final state E, n 0) of A + BC. This problem can be phrased as our asking for the amplitude of making a transition from a free state E, m 0) at t —> —oo to free state E, n 0 at t — oo. Since E, m+) is known to have evolved from E, m 0) and E, n ) is known to evolve to state E, n 0), the answer is given by the expansion coefficients of an outgoing state in terms of the incoming states. That is,... [Pg.26]

It is the presence of the uncertainty products that would state us that an interaction took place between the incoming quantum state and the quantum states from the slit (not explicitly incorporated) in Hilbert space leads to a scattered state combining both, one can easily understand the emergence of diffraction effects. It is not the particle model that will indicate us this result. The scattered quantum state suggests all (infinite) possibilities the quantum system has at disposal. One particle will only be associated with one event at best yet, the time structure of a set of these events may be the physically significant element (see Section 4.1). [Pg.59]

The incoming states planar wave states sustained by the Rubidium atom. The collimators allow separation in space base states 10) and 20) propagate along channels 1 and 2 < i(x) and 02(x) are the scattered states at DS-1 and, as the source state is the same and we take identical slit interaction potentials, these functions differ only in space origin. After interaction with the laser beam the base states label from 1) to 10> are sufficient for discussing several possibilities... [Pg.91]

We have already argued that the phenomena of Raman scattering and fluorescence cannot be distinguished from each other unless the system interacts with its thermal environment. Next we extend the model discussed in Section 18.3 to explicitly include thermal relaxation effects. Our model now consists of four levels The incoming state zrt) = 11, vi, ki) with energy fCin = -F ha>i mi = c ki ... [Pg.674]

The above procedure resembles the Lippmann-Schwinger method [106] for constructing the incoming state in scattering theory. [Pg.13]

The energy and state resolved tiansition probabilities are the ratio of two quantities obtained by projecting the initial wave function on incoming plane waves (/) and the scattered wave function on outgoing plane waves [F)... [Pg.61]

In an electron scattering or recombination process, the free center of the incoming electron has the functions Wi = ui U u, and the initial state of the free elechon is some function v/ the width of which is chosen on the basis of the electron momentum and the time it takes the electron to aiTive at the target. Such choice is important in order to avoid nonphysical behavior due to the natural spreading of the wavepacket. [Pg.230]

The spin state of a paramagnetic system with total spin S wiU lift its (25 + l)-fold degeneracy under the influence of ligand fields (zero-field interaction) and applied fields (Zeeman interaction). The magnetic hyperfine field sensed by the iron nuclei is different for the 25 + 1 spin states in magnitude and direction. Therefore, the absorption pattern of a particular iron nucleus for the incoming synchrotron radiation and consequently, the coherently scattered forward radiation depends on how the electronic states are occupied at a certain temperature. [Pg.503]

In a Rydberg state of any atom but H, when the distance, r, of the Rydberg electron from the ion core is greater than a core radius, rc, the potential is a coulomb potential, but for r < rc the potential is usually deeper than a coulomb potential. The effect of the deeper potential is that if an incoming coulomb wave scatters from the ion core, the reflected wave has a phase shift of nfi compared to what it would have if it scattered from a proton. In other words the standing wavefunction for all r > rc is given by... [Pg.415]

The states correspond to wave packet controlled in the far past and in the far future, respectively. Let us see what this means. In the absence of external time-dependent fields, the scattering component of the time-dependent wave function i/r(f) can be expanded in terms of either of the two sets of scattering states for example, those with incoming boundary conditions... [Pg.284]

The scattering states fulfilling outgoing (incoming) boundary conditions, i.e., which correspond to wave packets controlled in the past (future), are given by... [Pg.288]

To conclude, the scattering states with incoming boundary conditions, which correspond, in the far future, to Coulomb plane waves, are a linear combination of the states... [Pg.289]

As detailed in Section 5.1.2, the photoelectron distribution in a channel, identified by a parent ion a = Is, 2s, 2p is obtained by projecting the propagating wavefunction l (t) onto the helium scattering states, which satisfy incoming boundary conditions... [Pg.292]
