Question

In monolayer transition metal dichalcogenides (“die-chal-koh-jen-ides”), an analogue of this effect is represented by peaks centered on the K valleys on photoluminescence spectra. Bill Phillips and Hal Metcalf used a tapered design that heightened this effect near the source to compress an atomic beam’s velocity distribution. In Griffiths’s treatment of this effect’s intermediate form for “n equals two,” (10[1])degenerate perturbation theory is used to calculate the eight-by-eight W matrix whose first two eigenvalues are “five gamma plus or minus beta.” Lasers are tuned to the sum of the Doppler effect and this effect to cool atoms in this effect’s namesake slowers. (10[1])The magnitude of this effect equals “mu sub B,” times the Landé (-5[1])(“lahn-DAY”) g-factor, times (-5[1])the external field, (10[1])times (-5[1])m-sub-j. For historical reasons, this effect is “anomalous” when spin is non-zero. (-5[2])For 10 points, (10[1])name this shift in atomic (10[1])energy levels in the presence (10[1])of a magnetic (10[4])field. (10[2])■END■ (10[8]0[5])

ANSWER: Zeeman effect [accept anomalous Zeeman effect; accept Zeeman slower or Zeeman slowing or Zeeman cooling; accept valley Zeeman effect]
