TL;DR: In this paper, absolute photodetachment cross sections have been measured for the hydrocarbon chain anions C(n)H(-), n = 2, 4, and 6, which are relevant for an understanding of molecular clouds in the interstella.

TL;DR: Absolute total photodetachment cross sections of O(-) and OH(-) anions stored in a multipole radio frequency trap have been measured using a novel laser depletion tomography method to increase the accuracy of the widely used calibration standard for relative photodentachment measurements of diverse atomic and molecular species.

TL;DR: In this paper, the column density distribution of trapped OH− ions in a 22-pole ion trap is measured for different trap parameters and the density is obtained from position-dependent photodetachment rate measurements.

TL;DR: Mikosch et al. as mentioned in this paper showed that the storage time of a thermal ensemble of ions in a multipole radiofrequency (rf) ion trap is ultimately limited by ion evaporation.

TL;DR: In this paper, the column density distribution of trapped OH$^-$ ions in a 22-pole ion trap is measured for different trap parameters, and agreement is found with the effective potential of an ideal 22pole, but in addition, 10 distinct minima in the trapping potential indicate a breaking of the 22-fold symmetry.
