The new neutron-deficient isotope $$^{187}$$Po has been identified in the complete fusion reaction $$^{46}$$Ti+$$^{144}$$Sm $$rightarrow$$ $$^{187}$$Po+3n at the velocity filter SHIP of GSI. Striking features of the $$^{187}$$Po $$alpha$$ decay are the strongly-hindered decay to the spherical ground state and unhindered decay to a surprisingly low-lying deformed excited state at 286 keV in the daughter nucleus $$^{183}$$Pb. Based on the potential energy surface calculations, the $$^{187}$$Po ground state and the 286 keV excited state in $$^{183}$$Pb were interpreted as being of prolate origin.
