Decay properties of the new neutron-deficient nuclide At have been studied in the complete fusion reaction 
Sm(
V,3n)At at the velocity filter SHIP of GSI. Two isomeric states with half-lives of 88(6) ms and 11.5(6) ms, respectively, and with complex -decay schemes were identified in At. The decay pattern of one of the isomers suggests that it is based on the oblate-deformed 
2f7/2 
1i13/2 configuration, which confirms the expected onset of deformation in the At isotopes by approaching the neutron midshell at N=104.
