Hyperfine transition induced by atomic motion above a paraffin-coated magnetic film
Naota Sekiguchi, Hiroaki Usui, Atsushi Hatakeyama
We measured transitions between the hyperfine levels of the electronic ground state of potassium-39 atoms (transition frequency: 460 MHz) as the atoms moved through a periodic magn…
Spin-dependent metastable He () atom scattering from ferromagnetic surfaces: Potential application to polarized-gas production
Haruka Maruyama, Mitsunori Kurahashi, Kanta Asakawa +1
A spin-polarized triplet metastable helium (He*) beam has been used as a probe for surface magnetism, but changes in the spin state during scattering from a surface remain unclear.…
Measurement of the temperature dependence of dwell time and spin relaxation probability of Rb atoms on paraffin surfaces using a beam-scattering method
Kanta Asakawa, Yutaro Tanaka, Kenta Uemura +5
The scattering of Rb atoms on an anti-relaxation coating was studied. No significant change in the spin relaxation probability of Rb atoms by single scattering from a tetracontane…
Systematic studies of rubidium-exposed surfaces by X-ray photoelectron spectroscopy and light-induced atom desorption
Atsushi Hatakeyama, Sae Watashima, Ayumi Yamaguchi +6
We systematically investigated various types of surfaces on which rubidium (Rb) atoms were deposited by X-ray photoelectron spectroscopy (XPS) and measured the light-induced atom d…
Alkali ion-to-neutral atom converter for the magneto-optical trap of a radioactive isotope
Hirokazu Kawamura, Ken-ichi Harada, Tomoya Sato +12
We have developed a unique neutralizer device that uses an yttrium target surrounded by a platinum wall to magneto-optically trap radioactive atoms. In general, the radioactive nuc…
Detection of radiation torque exerted on an alkali-metal vapor cell
Atsushi Hatakeyama, Runa Yasuda, Yutaka Goto +3
We have developed a torsion balance to detect the rotation of a cell containing spin-polarized gaseous atoms to study angular momentum transfer from gaseous atoms to solid. A cesiu…
