Caesium 6P fine-structure mixing and quenching induced by collisions with ground-state caesium atoms and molecules
Applying the cw laser fluorescence method, the cross sections for the fine structure mixing and quenching of the Cs 6P state, induced by collisions with ground-state caesium atoms and molecules, have been measured. Caesium atoms were optically excited to the 5DJ states via quadrupole-allowed 6S1/2 → 5DJ transitions, while the resonance states were populated by the radiative and collisional 5DJ ...
متن کاملMixing and quenching of the Cs 5 D J states induced by collisions with caesium ground - state atoms ∗
Applying the cw laser absorption and fluorescence method the cross sections for the fine-structure mixing and quenching of the caesium 5DJ states have been measured in pure caesium vapour. Caesium atoms were optically excited to the 5D5/2 state via the quadrupole-allowed 6S1/2 → 5D5/2 transition. The ground-state caesium density N0, obtained from the absorption at the pumped quadrupole transiti...
متن کاملRubidium 5'P fine-structure transitions induced by collisions with potassium and caesium atoms
A diode-laser fluorescence experiment was performed in order to study fineStNCtUre transitions between 5'P states of rubidium atoms colliding with ground-state potassium or caesium atoms. The Rb(5'P,/,) state was optically excited and the intensity ratio of sensitized to direct fluorescence was measured. The obtained cross sections for the excitation energy transfer Rb('P,,J + Rb('PII2) induced...
متن کاملDipole force trapping of caesium atoms
A novel dipole force trap was developed for trapping caesium atoms in the lower hyperfine level of the ground state and in preliminary experiments a cloud of ≈1000 atoms was trapped. The viability of the trap is discussed, including suggestions for amendments to the trap design and problems that might occur which are intrinsic to the caesium atom.
متن کاملCaesium diuranium hexatelluride
Single crystals of CsU(2)Te(6) were synthesized from the reaction of U, Te, and Cs(2)Te(3) at 1273 K. CsU(2)Te(6) crystallizes in the space group Cmcm in the CsTh(2)Te(6) structure type. The asymmetric unit comprises one U (site symmetry m2m), one Cs (m2m; half-occupancy) and two Te atoms (m.. and m2m). The structure of CsU(2)Te(6) consists of infinite [U(2)Te(6)] layers perpendicular to [010] ...
