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...
The thresholds for these two processes are in good agreement with theoretically determined excitation energies. The cross section for spin-forbidden formation of ground state VS + ( 3 Σ − ) exhibits an unusual variation with kinetic energy that is attributed to the energy dependence of the ...

(BRs) for an isospin-forbidden and/or allowedparticle emission provide a stringent test and constraint for a microscopic approach that takes into account ofisospin non-conservation (INC) consistently in all considered physics processes, i.e., decay, proton emission andelectromagnetic de-excitation....
For Er3+ and Tm3+, upon excitation in the higher energetic 4f(n-1)5d states two kinds of f-d emission are observed: fast spin-allowed emission with a decay time in the order of ns, and slow spin-forbidden emission with a decay time in the order of mu s. These two types of f-...
Nearby, three triplet states are located, two n →π* states (T1 and T2), and a π→π* triplet excitation (T3). The experimentally observed strong absorption band with maximum at 3.96 eV arises from the π→π* excited 1B2 (S3) state. Computed radiative lifetimes are presented for...

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 A ) is favored over the spin-allowed transition CF ( B ← X A ). The selectivity is ...
