What is it about?
Cold atmospheric pressure plasma jets have a number of applications such as cancer treatment, wastewater treatment, and much more. Oxygen is a critical species for many of these applications. In this work, we report on the observation of a seldom seen oxygen line and highlight its importance to various subject areas in science.

Why is it important?
Atomic oxygen is routinely created in atmospheric pressure plasmas but not in the particular state that we observe. Our findings highlight an uncommon phenomenon which has implications for astrophysical research on comets and many technological applications.
