Excited states of 195At have been studied by means of in-beam γ -ray spectroscopy and the recoil-decay tagging technique. A strongly coupled rotational band feeding the α-decaying 7/2− state via unobserved transitions was identified. This band is presumably built on the oblate proton I π = 13/2+ state. Confirming earlier measurements, α decays from the 1/2+ and 7/2− states were observed. Additionally, an E3 branch competing with the α decay of the 7/2− state was inferred. Also α decays of the odd-odd isotopes 194,196At were examined.
