thumb|upright|The All-sky New Horizons Alice Lyα maps in ecliptic coordinates centered on the anti-Sun direction, and the lower map is in Galactic coordinates. The c. 90,000 stars in the M. A. Velez et al. (2024) catalog are overlaid as black dots, where the size of the dot is proportional to the logarithm of the expected Alice count rate from each star. The map in Galactic coordinates indicates the outlines of four of the important LISM clouds ("LIC", in red; "Aql" in green; "Blue", in blue; and "G", in tan). Lyman-alpha, typically denoted by Ly-α or Lyα, is a spectral line of hydrogen (

interaction between electrons, often complicating physical calculations

laser cooling technique

Autoionization is a process by which an atom or a molecule in an excited state spontaneously emits one of the outer-shell electrons, thus going from a state with charge  to a state with charge , for example from an electrically neutral state to a singly ionized state.
