High-resolution extreme-ultraviolet spectroscopy of potassium using anti-Stokes radiation.
We report the use of a new extreme-ultraviolet radiation source based on spontaneous anti-Stokes scattering for high-resolution absorption spectroscopy of transitions originating from the 3p(6) shell of potassium. The region from 546.6 to 536.8 A is scanned at a resolution of about 1.2 cm(-1). Within this region, four previously unreported lines are observed.
