Excited states in the ^70Kr and ^70Br nuclei were populated via the ^40Ca (^32S, 2n) ^70Kr and ^40Ca (^32S, pn) ^70Br fusion-evaporation reactions at the Accelerator Laboratory of the University of Jyv\"askyl\"a. The 2^+0^+ and 4^+2^+ transitions in ^70Kr have been found to be 881 (1) keV and (tentatively) 1037 (2) keV, respectively. Several new -ray transitions were also identified in ^70Br, and the T=1 band has been tentatively extended up to J^=10^+. The newly observed transitions in ^70Kr and ^70Br resolve discrepancies in the previously reported results for these nuclei. The experimental Coulomb, triplet, and mirror energy differences are compared with the results of two independent shell-model calculations. The comparisons aim to investigate the shape evolution and the role of the isospin breaking interactions in this mass region.
