The excitation-transfer reaction between N 2 (A 3 Σ u + ) and CF 2 (X 1 A 1 ) has been studied in a discharge-flow reactor. Dispersed emission spectra show that the spin-forbidden excitation CF 2 ( 3 B 1 ← X 1 A 1 ) is favored over the spin-allowed transition CF 2 ( 1...
Spin-forbidden excitation of CF 2( 3B 1 ← X 1A 1) by collisions with N 2(A 3Σ u+) The excitation-transfer reaction between N (A Σ ) and CF (X A ) has been studied in a discharge-flow reactor. Dispersed emission spectra show that the spin-forbidden excitation CF ( B ← X ...
The isospin-forbidden electroexcitation of the 1 −, T = 0 state at 7.12 MeV in 16O has been studied for momentum transfers q = 0.22 − 0.49 fm −1. The form factor at these momentum transfers is determined by the sum of the isospin T = 0 part and a T = 1 contribution. ...
From the excitation spectra of Br~+,two (2+1)REMPI spectral lines are discovered firstly and assigned as from the spin forbidden transitions 5P~4P_(3/2)、5P~4P_(5/2)←4P~2P_(1/2). 从Br+的分质量激发谱首次发现了Br的两条(2+1)REMPI谱线,归属为5P4P3/2←4P2P1/2和5P4P5/2←4P2P...
Absolute cross sections for near-threshold electron-impact excitation of Be-like C2+, N3+, and O4+ ions Absolute total cross sections for electron-impact excitation of the Be-like C2+, N3+, and O4+ ions have been measured near threshold using the merged elect... ME Bannister,N Djuri...
Luminescence spectra of lanthanides in the vacuum ultraviolet spectral region have revealed interesting features for 4fn↔4fn-15d (f-d) transitions. For Tb3+, Dy3+, Ho3+, Er3+, and Tm3+ in LiYF4, weak f-d bands are present in the excitation spectra at lower energy than the usually...
Interpretation of the 4f-5d Excitation Spectra of Eu3+ and Tb3+ Doped in Crystals The structure of the low-temperature 4fN→4fN−15d excitation spectra of Eu3+ and Tb3+ doped in crystals LiYF4, YPO4 and CaF2 measured by van Pieterson e... CC Duan - 《Journal of Rare Earths》 ...

Sequential two photon excitation of the C2 Swan transitions and C2 relaxation dynamics in rare gas solids The C2d3Πg–a3Πuemission in solid Ar and Ne is excited both by sequential absorption of two identical photons and by two unlike photons using two separat... Bondybey,E V. - 《Journa...
The excitation energy of the lowest 0 + T = 2 state in 28Si was measured to be 15.206 ± 0.025 MeV. The state decays predominantly by isospin-forbidden α-particle emission. Its analogue in 28Al was also observed at 5.983 ± 0.025 MeV. RL Mcgrath,JC Hardy,J Cerny - 《Physics Letters...
