چکیده

An experimental method is demonstrated that allows determination of the ratio between the electric (E1) and magnetic (M1) transition dipole moments in the A-X band of OH, including their relative sign. Although the transition strengths differ by more than 3 orders of magnitude, the measured M1-to-E1 ratio agrees with the ratio of the ab initio calculated values to within 3%. The relative sign is found to be negative, also in agreement with theory.

Communication: Magnetic dipole transitions in the OH A 2Σ+ ← X 2Π system.

We report on the observation of magnetic dipole allowed transitions in the well-characterized A (2)Σ(+) - X (2)Π band system of the OH radical. A Stark decelerator in combination with microwave Rabi spectroscopy is used to control the populations in selected hyperfine levels of both Λ-doublet components of the X (2)Π(3/2), v = 0, J = 3/2 ground state. Theoretical calculations presented in this ...

Dipole moment transitions in OH: theory

We consider Stark-decelerated molecules in the X Π3/2, J = 3/2, v = 0, f state, where X Π3/2 designates the electronic ground state of OH for which |Ω| = 3/2 is a nearly good quantum number. This is also called the F1 spinorbit manifold in the main text. Moreover, J is the eigenvalue of the angular momentum operator Ĵ = L̂ + Ŝ + R̂ with L̂ the electronic orbital angular momentum, Ŝ the electronic ...

Magnetic Dipole Transition in Atomic Ytterbium

We present the results of an ongoing investigation designed to measure the forbidden magnetic dipole transition amplitude for the 6s2 S0 → 6s5d D1 transition (408 nm) in atomic ytterbium. The transition is excited in an effusive atiomic beam with a C.W. laser in the presence of crossed D.C. electric and magnetic fields. The fields are arranged to provide interference between the magnetic dipole...

New possible manifestations of parity violation in forbidden magnetic transitions : chiral absorption of plane polarized light and circular dichroism in crossed transverse dc electric and magnetic fields

2014 In this paper, we shall present new approaches to the problem of finding a parity violation in forbidden magnetic transitions of heavy atoms. The basic principle is the observation of an interference between the electric dipole amplitude induced by the parity violating neutral currents interaction and the stark induced electric dipole amplitude in nS ~ n’ S radiative transitions. The new f...

The Effect of Annealing, Synthesis Temperature and Structure on Photoluminescence Properties of Eu-Doped ZnO Nanorods

In this study un-doped and Eu-doped ZnO nanorods and microrads were fabricated by Chemical Vapor Deposition (CVD) method. The effects of annealing, synthesis temperature and structure on structural and photoluminescence properties of Eu-doped ZnO samples were studied in detail. Prepared samples were characterized using X-Ray diffraction (XRD), scanning electron microscopy (SEM), particle size a...
