| Abstract: | We have measured the spectra of continuum X-rays above the characteristic K lines for 4.5 to 4.8 MeV/N 20882Pb → 20882Pb, Pb → Bi, Bi → Pb and Bi → Bi collisions. Above ≈400 keV X-ray energy the spectral shape and intensity agree roughly with calculations of Kirsch et al. for the 1sσ molecular-orbital (MO) X-ray spectrum from Pb-Pb. Deviations from the theory below ≈400 keV suggest transitions to other MO's. |
