Hyperfine structure and isotope shift measurements
The 4d S0 ground-state transitions to the 4d 9 5p configuration of palladium (Pd) have been studied. For this purpose, a tunable, single-mode, deep-UV cw laser has been built to generate the sum frequency of a frequency-doubled Ti:S laser with a second Ti:S laser. The produced wavelengths range from 244 to 276 nm. From the measured spectra the frequency splitting due to hyperfine structure and ...
متن کاملPrecise fine-structure and hyperfine-structure measurements in Rb
We demonstrate a new technique for measuring the absolute frequencies of atomic transitions. The technique uses a ring-cavity resonator whose length is calibrated using a reference laser locked to the D2 line in Rb. The frequency of this line is known to be 384 230 484.468(10) MHz. Using a second laser locked to the D1 line of Rb, we measure the frequencies of various hyperfine transitions in t...

متن کاملHyperfine Structure Measurements of Antiprotonic Helium and Antihydrogen
This paper describes measurements of the hyperfine structure of two antiprotonic atoms that are planned at the Antiproton Decelerator (AD) at CERN. The first part deals with antiprotonic helium, a three-body system of α-particle, antiproton and electron that was previously studied at LEAR. A measurement will test existing three-body calculations and may – through comparison with these theories ...
متن کاملThe Role of the Hyperfine Structure for the Determination of Improved Level Energies of Ta II, Pr II and La II
For the determination of improved energy levels of ionic spectra of elements with large values of nuclear magnetic dipole moment (and eventually large values of nuclear quadrupole moments), it is necessary to determine the center of gravity of spectral lines from resolved hyperfine structure patterns appearing in highly resolved spectra. This is demonstrated on spectral lines of Ta II, Pr II an...
