Comment on "Electron collisional excitation of argon-like Ni XI using the Breit-Pauli R-matrix method" [Eur. Phys. J. D 42, 235-241 (2007)] - Electron impact excitation of Ni XI

In a recent paper, Verma et al. [Eur. Phys. J. D 42, 235 (2007)] have reported results for energy levels, radiative rates, collision strengths, and effective collision strengths for transitions among the lowest 17 levels of the (1s(2)2s(2)2p(6))3s(2)3p(6), 3s(2)3p(5)3d and 3s3p(6)3d configurations of Ni XI. They adopted the CIV3 and R-matrix codes for the generation of wavefunctions and the scattering process, respectively. In this paper, through two independent calculations performed with the fully relativistic DARC (along with GRASP) and FAC codes, we demonstrate that their results are unreliable. New data are presented and their accuracy is assessed.

[review] Ulrich LEISINGER (ED.), Bach: Messe in h-Moll BWV 232 (Stuttgart: Carus, [2014]), 312 pp + 1 DVD-ROM, ISMN: 9790007142599, €199

This latest edition of J. S. Bach’s B-minor Mass, by Ulrich Leisinger, described by the publisher as a ‘hybrid edition’, aptly addresses the needs of present-day performers and at the same time fulfils the scholarly expectations of new critical editions to conform to the current study environment
