Abstract

Photodetachment microscopy has been used in a double-pass, field-collinear scheme in order to measure the electron affinity of atomic oxygen. As an illustration of the sensitivity of the method, electron images could be recorded even from the rarest ¹⁷O^\ensuremath- ion. Analysis of photodetachment images recorded with this odd isotope, however, requires that one knows the unresolved hyperfine structures of the ground states of both the neutral atom ¹⁷O and the negative ion. Calculation of the hyperfine structure of ¹⁷O^\ensuremath- was achieved, which permitted to add the electron affinity of ¹⁷O to the series of the measured electron affinities of oxygen isotopes. The anomalous isotope shift of these electron affinities is finally compared with ab initio calculations.
