In a recent experiment [Andersen et al., Phys. Rev. Lett. 79, 4770 (1997)], the [Formula Presented] photodetachment cross section (PDCS) and resonances are measured to high precision. Detailed resonance profiles are obtained. To make a critical comparison with experiment, the [Formula Presented] PDCS below the [Formula Presented] and [Formula Presented] thresholds is calculated with a saddle-point complex-rotation method. The theoretical PDCS are convoluted with a Gaussian profile using experimental resolution for full width at half maximum. The theoretical results are calculated with length, velocity, and acceleration gauges. They are compared with the precision data in the literature. Improved widths are obtained for some of the narrow resonances below the [Formula Presented] threshold.
