Abstract The Doppler shift and the anisotropy of the MO X-rays above the separated-atomK-lines have been measured in208Pb+208Pb and209Bi+209Bi collisions at beam energies between 4.2 and 4.8 MeV/u. The Doppler shift is found to be consistent with a source moving with 90% of the center of mass velocity of the colliding system. One peak is observed in the anisotropy spectrum. This peak might be attributed to transitions from the continuum into the minimum of the 2p 1/2 σ MO or from the 3p 1/2 σ and 2p 3/2 σ MO's into the 2 sσ MO near the united atom limit. Radiative electron capture and secondary electron bremsstrahlung could be excluded as major sources of the observed radiation. Contrary to lighter systems no anisotropy corresponding to transitions into the 1 sσ orbital could be observed.
