  Detailed abundances of the elements produced by r-process nucleosynthesis in
various circumstances are our best observational clues to their origin, since
the site(s) of r-element production is(are) still not known with certainty. A
small fraction of extremely metal-poor (EMP) stars exhibit excesses of heavy
neutron-capture elements produced in the r-process, and CS 31082-001 is among
the 4 well-known r-process-enhanced EMP stars. Observations with HST/STIS
provide abundances for elements observable only from the UV region. Here we aim
to supplement the optical data with abundances from near-UV spectroscopy of the
first and second peak of the r-elements, which are crucial to giving insight
into the nucleosynthesis of the elements beyond iron. The UVES spectrum
provided additional measurements, thereby improving the previous results. The
spectra were analyzed with the OSMARCS LTE model atmosphere and with a
consistent approach based on the spectrum synthesis code Turbospectrum to
derive abundances of heavy elements in CS 31082-001, using updated oscillator
strengths from the recent literature. We computed synthetic spectra for all
lines of the elements of interest, checking for proper intensities and possible
blends. We combined the abundances of heavy elements derived in previous works
with the derivation of abundances from all reliable new list of lines, for the
first and second peaks of r-elements. We were able to derive new abundances for
23 n-elements, 6 of them - Ge, Mo, Lu, Ta, W, and Re - were not available in
previous works, making this star the most complete r-II object studied, with a
total of 37 detections of n-capture elements. We also present the first NLTE+3D
lead abundance in this star. The results provide improved constraints on the
nature of the r-process.
