Electronic, optical and thermoelectric properties of sodium pnictogen chalcogenides: A first principles study

Autor: Khare, I. S., Szymanski, N. J., Gall, D., Irving, R. E.

Ternary chalcogenides have been of recent investigation for applications in photovoltaic and thermoelectric devices. We study the structural, electronic, optical, and thermoelectric properties of nine ternary chalcogenides, NaAX$_{2}$, where A repres

Lifetimes and Oscillator Strengths for Ultraviolet Transitions in Neutral Chlorine

Autor: Alkhayat, R. B., Irving, R. E., Federman, S. R., Ellis, D. G., Cheng, S.

We present lifetime measurements using beam-foil techniques for radiative transitions from the 3$p^4$($^1S$)4$s$ $^2S_{1/2}$, 3$p^4$($^3P$)5$s$ $^2P_{1/2,3/2}$, and 3$p^4$($^3P$)3$d$ $^2F_{5/2}$ levels in Cl I and the corresponding results of the osc

Oscillator Strengths for Ultraviolet Transitions in P II -The Multiplet at 1308 {\AA}

Autor: Brown, M. S., Alkhayat, R. B., Irving, R. E., Heidarian, N., Brown, J. Bancroft, Federman, S. R., Cheng, S., Curtis, L. J.

We report lifetimes, branching fractions, and the resulting oscillator strengths for transitions within the P II multiplet (3s23p2 3P - 3s3p3 3Po) at 1308 {\AA}. These comprehensive beam-foil measurements, which are the most precise set currently ava

Lifetimes and Oscillator Strengths for Ultraviolet Transitions in Singly-Ionized Tin

Autor: Heidarian, N, Irving, R E, Federman, S R, Ellis, D G, Cheng, S, Curtis, L J

Publikováno v: Journal of Physics B: Atomic, Molecular and Optical Physics, 2016, Volume 49, Number 21

Lifetime measurements using beam foil techniques for the $5s5p^{2}$ $^{2}D_{3/2,5/2}$ levels in Sn II are presented. The resulting oscillator strengths for transitions at 1699.4, 1831.8 and 1811.2 \AA{} are reported. We also studied these levels with

Oscillator Strengths for Ultraviolet Transitions in P II

Autor: Federman, S. R., Brown, M., Torok, S., Cheng, S., Irving, R. E., Schectman, R. M., Curtis, L. J.

Publikováno v: Astrophys.J.660:919-921,2007

We report lifetimes, branching fractions, and the resulting oscillator strengths for transitions within the P II multiplet (3s^23p^2 ^3P - 3s^23p4s ^3P^o) at 1154 A. These beam-foil measurements represent the most comprehensive and precise set curren
