Abstract

The high-resolution photoelectron spectra of Co^\ensuremath- were obtained via the slow-electron velocity-map imaging method. The electron affinity of cobalt element was determined to be 5341.45(37)\phantom\rule0.16em0excm^\ensuremath-1 or 662.256(46) meV. The fine structure of Co^\ensuremath- was well resolved. The fine-structure intervals Co^\ensuremath-(³F₄)\ensuremath-Co^\ensuremath-(³F₃) and Co^\ensuremath-(³F₄)\ensuremath-Co^\ensuremath-(³F₂) were found to be 920.9(6)\phantom\rule0.16em0excm^\ensuremath-1 and 1550.3(9)\phantom\rule0.16em0excm^\ensuremath-1, respectively. The accuracy was improved by a factor of more than ten with respect to the previous laser photodetachment threshold measurement.
