چکیده

We have measured the circular polarization of light emitted from both atomic H and molecular H2 after bombarding H2 with longitudinally polarized electrons. For both atomic and molecular fluorescence near threshold we observe a circular polarization as great as 10% of the electron polarization. This represents the first direct observation of spin transfer in electron-molecule collisions.

(2+1) laser-induced fluorescence of spin-polarized hydrogen atoms.

We report the measurement of the spin polarization of hydrogen (SPH) atoms by (2+1) laser-induced fluorescence, produced via the photodissociation of thermal HBr molecules with circularly polarized 193 nm light. This scheme, which involves two-photon laser excitation at 205 nm and fluorescence at 656 nm, offers an experimentally simpler polarization-detection method than the previously reported...

Laser Driven Polarized H/D sources and targets

Traditionally, Atomic Beam Sources (ABSs) are used to produce targets of nuclear polarized Hydrogen (H) or Deuterium (D) for experiments using storage rings. Laser-Driven Sources (LDSs) o er a factor of 20-30 gain in the target thickness (however, with lower polarization) and may produce a higher overall gure of merit. The LDS is based on the technique of spin-exchange optical pumping where alk...

Mapping spin coherence of a single rare-earth ion in a crystal onto a single photon polarization state.

We report on optical detection of a single photostable Ce(3+) ion in an yttrium aluminium garnet (YAG) crystal and on its magneto-optical properties at room temperature. The spin quantum state of the emitting level of a single cerium ion in YAG can be initialized by a circularly polarized laser pulse. Coherent precession of the electron spin is read out by observing temporal behavior of circula...

Magnetic circular dichroism in the L2,3 x-ray fluorescence of Fe and Co

the L2,3 x-ray fluorescence spectra of magnetized Fe and CO excited by circularly polarized synchrotron radiation exhibit magnetic circular dichroism. The results are compared to the energy resolved spin polarized densities of states given by first-principles calculations.

Circularly Polarized Circular Slot Antenna Array Using Sequentially Rotated Feed Network

This paper presents the design, simulation, and measurement of two low-cost broadband circularly polarized (CP) printed antennas: a single element and an array at C band. The proposed single element antenna is excited by an L-shaped strip with a tapered end, located along the circular-slot diagonal line in the back plane. From the array experimental results, the 3 dB axial ratio bandwidth can r...
