Description
Different neutral and charged interstellar molecules constitute the building blocks for a rich reaction network in the interstellar medium (ISM). The abundance of negative ions in the ISM and their role in the chemistry of these environments has been subject to long-standing discussions in astrochemistry. Photodetachment cross-section studies are crucial for predicting the abundance of anions in the ISM. In our experiments we aim to study the threshold photodetachment spectroscopy of C2- and C2H- which are speculated to exist in the ISM, in a 16-pole radiofrequency ion trap, which can be cooled down to 6 K to mimic conditions in the ISM. The status of the experiment will be presented.
