    "abstract": "The absolute photodetachment cross section of OH- anions at a rotational and\ntranslational temperature of 170K is determined by measuring the\ndetachment-induced decay rate of the anions in a multipole radio-frequency ion\ntrap. In comparison with previous results, the obtained cross section shows the\nimportance of the initial rotational state distribution. Using a tomography\nscan of the photodetachment laser through the trapped ion cloud, the derived\ncross section is model-independent and thus features a small systematic\nuncertainty. The tomography also yields the column density of the OH- anions in\nthe 22-pole ion trap in good agreement with the expected trapping potential of\na large field free region bound by steep potential walls.",
