چکیده
We present the Multichannel Quantum Defect Theory in its operatonal form and its application to the problem of Rydberg states of a diatomic molecule in extemal electnc fields. The theoretical analysis consists m the description of the close connection between the resolvent operator and the Density-Of-State matrix which defines the whole spectrum In the particular case of the discrete spectrum in weak electnc fields, bound states are deduced from the poles of

Autoionizing Rydberg states of NO in strong electric fields
We report on an investigation on autoionization of Rydberg electrons of the nitric oxide molecule in strong, static electric fields. The excitation was done via various rotational states of the A S intermediate state (v850) and with polarization parallel or perpendicular to the electric field. The splitting of the autoionizing Rydberg states into overlapping Stark manifolds is resolved for exci...
متن کاملThe Stark effect in Rydberg states of a highly polar diatomic molecule: CaF.
The Stark effect in molecular Rydberg states is qualitatively different from the Stark effect in atomic Rydberg states because of the anisotropy of the ion core and the existence of rotational and vibrational degrees of freedom. These uniquely molecular features cause the electric-field-induced decoupling of the Rydberg electron from the body frame to proceed in several stages in a molecule. Be...
متن کاملAnalysis of Electric Field and Polarization of SF6 Circuit Breaker to Approach a Suitable Structure
Abstract: The application of electric field theory to widely different aspects of electrical insulation has led to more understanding the phenomena. Electric fields may be considered as the main reason for insulation failure. The purpose of this paper is to modify importance of analyzing electric field in insulation design. The SF6 circuit breaker is chosen as case study that encounters cri...
متن کاملHigh-resolution millimeter wave spectroscopy and multichannel quantum defect theory of the hyperfine structure in high Rydberg states of molecular hydrogen H2.
Experimental and theoretical methodologies have been developed to determine the hyperfine structure of molecular ions from detailed studies of the Rydberg spectrum and have been tested on molecular hydrogen. The hyperfine structure in l=0-3 Rydberg states of H2 located below the X 2Sigmag+(v+=0,N+=1) ground state of ortho H2+ has been measured in the range of principal quantum number n=50-65 at...
متن کاملThe spectroscopy of bound and predissociating Rydberg states of NO in external electric fields
This thesis reports the application of static and ramped electric fields to the Rydberg states of NO. Chapter 1 introduces the history of Rydberg states, their exotic properties, decay mechanisms, and the effect of an applied electric field. Chapter 2 details the experimental set-up used for the experiments presented in this thesis. Chapter 3 describes the structure of NO and multiphoton excita...
