Description
In this report I’ll tell about our activities within a project supported from Latvian Council of Sciences “Laser Photodetchment Threshold Spectroscopy of Negative Ions“. Within our project the participation in 3 different experiments from the list of active experiments on ISOLDE. Firstly Electron Affinity measurements on Clorine [1], and Polonium [2] as next. And latr we joined the parity non conservation studies on negative ions [3].
Due to our expertise in isotope shift measurements in electron affinities of Chlorine [4] we were invited to join the MIRACLS group [5] working on trapping the Chlorine anions during summer 2022. In early 2024 experiments were continued on GANDALPH [6]. I have to mention that the results recently were submitted in Nature Communication and will be published there in nearest future.
Finally, I’ll report on our experimental facility in the lab at University of Latvia, and I will reveal my vision for our future experiments.
