In the scattering of H+ by rare gases, some effects in the elastic cross sections are observed which can be explained by the influence of the potential of the chargeexchanged particles, using the SLZ-model. The structure in the elastic cross sections for H2+-Kr can be explained as a ...
Stochastic Landau-Zener model, and experimental estimates of dephasing time in molecular magnetsMolecular magnetsMuon spin rotation and relaxationQuantum tunneling of the magnetization in magnetic molecules (MM) with high spin value is a fascinating subject which contrasts clean and accurate experimental ...
A model of quantum dynamics of nonadiabatic transition in energy crossing two-level systems (Landau-Zener model) with fluctuation and dissipation mechanisms is formulated on the basis of the damping theory. The model is composed of a two-level system interacting with a single-mode boson system wh...
We analyze the applicability of a simple two-level Landau–Zener model to describe the evolution of the probability amplitudes in this realistic system. We show that the Landau–Zener model works very well when it is viewed in the adiabatic basis, but it is not as robust in the diabatic ...
Scattering processes of atoms, molecules and ions with two crossing electronic potentials may be treated in the Stueckelberg-Landau-Zener-(SLZ) model. In this paper the WKB-solutions for the radial wave functions, given by Stueckelberg are used to calculate differential cross sections. The effects...

We present details about an experimental method based on the Landau–Zener model which allows one to measure very small tunnel splittings Δ in molecular clusters Fe[sub 8]. The measurements are performed with an array of microsuperconducting quantum interference devices. The observed oscillations of...
This paper presents analytic formulas for various transition times in the Landau-Zener model. Considerable differences are found between the transition times in the diabatic and adiabatic bases, and between the jump time (the time for which the transition probability rises to the region of its asymp...
