Abstract

In the analysis of condensed matter samples, electron spin resonance is a common experimental technique. ESR spectroscopy could become a versatile tool to investigate oligomers formed on He droplets after an examination of spin lifetimes and the development of a detection method for spin states. This paper reports the first magnetic study of any species in or on helium droplets as well as approximate relaxation times for electron spin states of potassium atoms and molecules on helium droplets.
