Atomic line self‐broadening was observed in ultracold cesium. Using resonant ionization detection we were able to photoassociate atoms into excited states of ultracold molecules below the second excited PJ atomic asymptotes Cs(6S1/2) + Cs(7P1/2) and Cs(6S1/2) + Cs(7P3/2). We were able to observe blue detuned satellite band features at 560 MHz and 800 MHz above the 7P1/2 and 7P3/2 atomic limits, respectively, as well as sharp hyperfine split features on the blue and red side of the atomic resonances. Such spectral features can be qualitatively supported by the local maxima in the long range molecular structure beyond 50 Å.
