Abstract: To date, a surprisingly large number of twelve trans-Fe elements were detected in the hot helium-rich WD RE0503–289, a phenomenon that is not observed in any other WD. Abundance analyses for most of these elements are hampered by the lack of atomic data for the relevant ionisation stages (iv–vii). To solve this problem, we perform experimental and theoretical work.
