    "abstract": "We investigate photodetachment from negative ions in a homogeneous 1.0-T\nmagnetic field and a parallel electric field of approximately 10 V/cm. A\ntheoretical model for detachment in combined fields is presented. Calculations\nshow that a field of 10 V/cm or more should considerably diminish the Landau\nstructure in the detachment cross section. The ions are produced and stored in\na Penning ion trap and illuminated by a single-mode dye laser. We present\npreliminary results for detachment from S- showing qualitative agreement with\nthe model. Future directions of the work are also discussed.",
