Nuclear quadrupole interaction and zero first-order Zeeman transitions of $^{167}$ Er $^{3 +}$ in CaWO $_{4}$

Lewin Marsh, Yikai Yang, Cesare Mattiroli +5

We report microwave spectroscopy of $^{167}$ Er $^{3 +}$ doped in CaWO $_{4}$ which reveals the hyperfine splitting of the erbium electronic ground state ( $Z_{1}$ , $J_{eff.}$ =15/2)…

Beam-tracing and profile evolution for localised beams in inhomogeneous plasmas

Lewin B. S. Marsh, Felix I. Parra, Valerian H. Hall-Chen +1

We derive the beam tracing and profile evolution for the propagation of any localised beam with arbitrary profile through an inhomogeneous cold plasma. We recover standard Gaussian…
