cds-question@unistra.fratomic-physicsAs part of the IRON Project, radiative rates have been calculated for the E1, E2 and M1 transitions within the n=2 complex in ions of the boron isoelectronic sequence (6<=Z<=28). The computations have been carried out with the atomic structure code SUPERSTRUCTURE which facilitates the generation of extended radiative datasets including configuration interaction, Breit-Pauli relativistic contributions and semi-empirical term-energy corrections. By means of extensive comparisons with the available datasets for this sequence, with detailed single-ion calculations and recent experiments, we have been able to assign accuracy ratings to the present A-values. We find that in general the spin-allowed and spin-forbidden E1 transitions are accurate to 10% and 20%, respectively, except for a few transitions in ions with Z<=7 that are perturbed by admixture with low-lying n=3 states (e.g. 2s^2^3l) and for those affected by the avoided crossing of the 2s2p^2^ ^2^S1/2 and ^2^P1/2 which takes place at Z~22. It is concluded that, statistically, the present dataset is the most accurate to date for this astrophysically relevant sequence.1998A&AS..131..499Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/131/499CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/103/273 : IRON Project II IR collision strengths of C-like ionsJ/A+A/283/319 : IRON Project III B-like ionsJ/A+AS/108/1 : IRON Project V Collision strengths of O-like ionsJ/A+A/293/953 : IRON Project VI Fe II collision strengthsJ/A+A/293/967 : IRON Project VII Fe II radiative transitionsJ/A+AS/109/193 : IRON Project VIII Electron excitation of Ti-like ionsJ/A+AS/119/509 : IRON Project XVII Radiative transition in Fe IIIJ/A+AS/119/523 : IRON Project XVIII Electron impact for Fe IIIJ/A+AS/120/361 : IRON Project XIX Fe II radiative transitionsJ/A+AS/123/159 : IRON Project XXII C and O radiative ratesJ/A+AS/123/575 : IRON Project XXIII Fe XXII excitation rate coefficientsJ/A+AS/126/373 : IRON Project XXVII Fe IV collision strengthsJ/A+AS/131/153 : IRON Project XXXI Fe XII electron excitationJ/A+AS/135/347 : IRON Project XXXV Fe XXIV & Fe XXV oscillator strengthsJ/A+AS/136/395 : IRON Project XXXVII Fe VI collision strengthsJ/A+AS/137/165 : IRON Project XXXVIII Fe XV electron excitationJ/A+AS/143/483 : IRON Project XLII Fe XXI electron impact excitationJ/A+AS/144/141 : IRON Project XLIII Fe V transition probabilitiesJ/A+AS/147/111 : IRON Project XLIV Fe VI trans. prob. & line ratioJ/A+AS/147/253 : IRON Project XLV Ar XIII, Fe XXI trans. probabilitiesJ/A+A/365/268 : IRON Project XLVII Ni III electron impact excitationJ/A+A/372/1078 : IRON Project XLIX Fe XX electron impact excitationJ/A+A/372/1083 : IRON Project L Fe XIX electron impact excitationJ/A+A/394/753 : IRON Project LI Fe IX electron impact excitationJ/A+A/408/789 : IRON Project LIII Fe XVII transition probabilitiesJ/A+A/413/779 : IRON Project LIV Fe XX transition probabilitiesJ/A+A/420/763 : IRON Project LV Ni II electron impact excitationJ/A+A/437/345 : IRON Project LIX Fe IV transition probabilitiesJ/A+A/448/779 : IRON Project LXI Fe IV radiative transitionsJ/A+A/457/721 : IRON Project LXII Fe XVIII allowed and forbidden trans.J/A+A/466/763 : IRON Project LXIII Fe^19+^ electron impact excitationhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/131/499https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/131/499http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/131/499https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/131/499https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/131/499http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/131/499GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+AS/131/499/acdsTransition probabilities for ions with Z=6 to Z=28recnoRecord number assigned by the VizieR team.
