RF phase effect in the ion-guide laser ion source (IG-LIS)
Ruohong Li, Maryam Mostamand, Jens Lassen
The effect of the phase between the radio frequency (RF) waveform driving the ion guide and the laser pulses generating ions on the intensity of the transmitted ion beam has been s…
Resonant Ionization Laser Ion Source (RILIS) Development on Lu and Pr
R. Li, J. Lassen, F. Ames +5
Resonance ionization laser ion sources are efficient and element selective ion sources, which are particularly well suited for radioactive ion beam facilities. Using TRIUMF's off-l…
Study of even-parity Rydberg and autoionizing states of lutetium by laser resonance ionization spectroscopy
R. Li, J. Lassen, Z. P. Zhong +6
Multi-step laser resonance ionization spectroscopy of lutetium (Lu) has been performed at TRIUMF's off-line laser ion source test stand. The even-parity Rydberg series $^2…
Isotope Shift Measurements of Stable and Short-Lived Lithium Isotopes for Nuclear Charge Radii Determination
W. Nörtershäuser, R. Sánchez, G. Ewald +18
Changes in the mean-square nuclear charge radii along the lithium isotopic chain were determined using a combination of precise isotope shift measurements and theoretical atomic st…
