The Al I absorption spectrum obtained with a flash-pyrolysis technique combined with BRV source was observed in the grazing-incidence region between 140 and 650 Å. Thirty-three new lines in the range 140–160 Å were recorded. A theoretical interpretation identifies 25% of the observed lines, accounting for half the observed intensity as 2p63s23p-2p53s23p4s transitions.
