Polarization measurements of the $2s$--$2p_{3/2}$ VUV transition in N${}^{4+}$ excited by electron collisions

Nobuyuki Nakamura, Ryohko Ishikawa, Motoshi Goto

We present the linear polarization of the $2s$--$2p_{3/2}$ transition in Li-like N${}^{4+}$ excited by electron collisions, measured at electron energies between 85 and 1000~eV. The…
