Ss. Churilov et Yn. Joshi, Observation of the strongest 5s(2) 5p(6) 5d-(5s(2) 5p(5) 5d6s+5s(2)5p(6) 7p) transitions in Au XI to Bi XV ions, PHYS SCR, 63(5), 2001, pp. 363-366
The spectra of gold till bismuth were studied in the 90-135 Angstrom region
. Nine most intense lines belonging to the 5s(2) 5p(6) 5d-5s(2) 5p(5) 5d6s
array were identified in Au XI to Pi XV ions. The 5s(2) 5p(6) 7p P-2(3/2),
(1/2) levels in Au XI and the 5s(2) 5p(6) 7p P-2(3/2) level in Hg XII were
also identified. The observed wavelengths and intensities agree quite well
with the Hartree-Fock calculations.
