Hyperfine dependent $gf$-values of Mn I lines in the 1.49 $-$ 1.80 $\mu$m H-band

Martin Andersson, Jon Grumer, Nils Ryde +5

The three Mn I lines at 17325, 17339 and 17349 Å~are among the 25 strongest lines ($\log (gf)>0.5$) in the H-band. They are all heavily broadened due to hyperfine structure and the…
