Lifetime measurement of the 6s level of rubidium

چکیده
We present a lifetime measurement of the 6s level of rubidium. We use a time-correlated single-photon counting technique on two different samples of rubidium atoms, a vapor cell with variable rubidium density, and a sample of atoms confined and cooled in a magneto-optical trap. The 5P1/2 level serves as the resonant intermediate step for the two-step excitation to the 6s level. We detect the decay of the 6s level through the cascade fluorescence of the 5P3/2 level at 780 nm. The two samples have different systematic effects, but we obtain consistent results that averaged give a lifetime of 45.57±0.17 ns.

متن کاملLifetime and hyperfine splitting measurements on the 7s and 6p levels in rubidium
We present lifetime measurements of the 7S1/2 level and the 6p manifold of rubidium. We use a timecorrelated single-photon counting technique on a sample of 85Rb atoms confined and cooled in a magneto-optic trap. The upper state of the 5P1/2 repumping transition serves as the resonant intermediate level for twophoton excitation of the 7s level. A probe laser provides the second step of the exci...

In this study, the adsorption of cesium, strontium, and rubidium radionuclides by ferritin magmolecules in a batch system was investigated under different experimental conditions. The experiments were conducted in a pilot plant that involved the contactor unit and the magnetic separator unit. The impact of the pollutant concentrations, adsorbent concentration, and pH on the efficiency of the pr...
متن کاملPhotoionization and imaging spectroscopy of rubidium atoms attached to helium nanodroplets.
Highly excited states of rubidium (Rb) atoms attached to helium (He) nanodroplets are studied by two-photon ionization spectroscopy in combination with electron and ion imaging. We find high yields of RbHe and RbHe(2) exciplexes when exciting to the 4D and 6P bands but not at the 6S band, in accord with a direct formation of exciplexes in binding RbHe pair potentials. Photoion spectra and angul...
متن کاملActivity– level as a link between customer retention and consumer lifetime value
Customer activity has received more attention due to the increase of social network applications. Moreover, customer activity could be an answer to the research debate about the significant relationship between retention rate and lifetime profitability of customers. Several researchers believe that an increase in the retention rate of customers may enhance their customer lifetime value (CLV), o...
