Transitions in boronlike Ni XXIV, Kr XXXII and Mo XXXVIII and fluorinelike Zr XXXII and Mo XXXIV, observed in the JET tokamakFunded under: FP3-FUSION 11C
Spectra of highly ionised Ni, Ge, Kr and Mo obtained from the JET tokamak have been studied. In total 20 new lines have been classified as n = 2, Delta-n = 0 transitions in B-like and F-like ions. Among the identified lines are M1 transitions within the 2s(2)2p(5) (2)P ground term of F-like Zr and Mo and within the 2s(2)2p (2)P ground term of B-like Mo. Furthermore, for B-like Ni, Kr and Mo, the 2s2p(2) (4)P(1/2) and (4)P(5/2) levels, which decay by spin-forbidden transitions, have been found. From the observed wavelengths, 20 new energy levels were determined. The experiments have been complemented with multiconfiguration Dirac-Fock (MCDF) calculations and semiempirical analyses of transition energies in the B I and F I isoelectronic sequences.
