    "abstract": "The specific mass shift in the electron affinity between ^{35}Cl and ^{37}Cl\nhas been determined by tunable laser photodetachment spectroscopy to be\n-0.51(14) GHz. The isotope shift was observed as a difference in the onset of\nthe photodetachment process for the two isotopes. In addition, the electron\naffinity of Cl was found to be 29138.59(22) cm^{-1}, giving a factor of 2\nimprovement in the accuracy over earlier measurements. Many-body calculations\nincluding lowest-order correlation effects demonstrates the sensitivity of the\nspecific mass shift and show that the inclusion of higher-order correlation\neffects would be necessary for a quantitative description.",
