Ni scheme 1

Notes

Ionization scheme developed by Trappitsch et al. using the CHILI instrument. Saturation curve were published in PhD thesis.

AI state for ionizing transition determined after Page and Gudemann (1990) J Opt Soc Am B 7:1761.

Scheme

Ionization Potential: 61619.770 cm⁻¹ (NIST ASD, 2024)
