Population Inversion and Continuous Optical Maser Oscillation in a Gas Discharge Containing a He-Ne Mixture
Open accessAbstract
cos'8 sin'8.However, for Fe'+ ions in MgO the cubic field causes a small admixing of states' and consequently, a slight deviation of the transi- tion probability from a simple cos'8 sin'6t de- pendence.Therefore, exact wave functions have been used in computing the theoretical angular variation.A quadrupole spin operator cannot induce transitions between pure -1/2 and+1/2 states, and the near-zero ultrasonic effect observed on this transition for all three ions is further evi- dence for the quadrupole interaction.The authors would like to thank Dr. G. D. Wat- kins for helpful discussions, and Mr. T. G.Kazyaka for his aid in taking the data.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
