| Abstract: | The hyperfine structure and isotope shifts of short-lived gold isotopes with 185 ≤ A ≤190 and the l1-/2 isomer of 189Au have been investigated by application of on-line resonance ionization mass spectroscopy. A detection efficiency of ε = 10-8 for gold atoms was observed at a background of about one event per 1000 laser shots. The deduced charge radii show a drastic change between A=187 and A=186 which is interpreted as an onset of strong deformation (β2 ≈ =0.25) in 186Au and 185Au due to the influence of the πlh(9/2) intruder orbital. |
