This work presents data obtained from optogalvanic spectroscopy (OGS) of dysprosium (Dy) using a commercial hollow cathode lamp. Combining laser beams from two tunable dye lasers, it was possible to identify 13 electronic transitions from excited sta

Modern technologies depend on Rare-Earth elements, and they can be further improved using isotopic enriched/pure materials. This work brings the first successful attempt to enrich 163Dy by AVLIS (Atomic Vapor Laser Isotope Separation) in Brazil.

In this work we propose an experimental apparatus to investigate the isotope shift using two sub-Doppler techniques: Intermodulated Laser Induced Fluorescence and Intermodulated Optogalvanic Spectroscopy. The experimental set uses a portable hollow c

In this work, we report a newly observed isotope shift between 162Dy and 164Dy isotopes for the 0 → 16 717.79 cm−1 (598.003 nm) optical transition. We compared the newly observed results against two other lines (597.452 nm and 598.859 nm), which

In this work, we suggest a methodology to determine the impact parameter for neutral dysprosium emission lines from the characterization of the plasma generated by laser ablation in a sealed chamber filled with argon. The procedure is a combination o
