The line and continuum intensities deduced from the multislit spectra of the (Fex) coronal emission line taken at the 1980 eclipse are used to discuss the relative roles of radiative and collisional excitation mechanisms. It is shown that for R/R o < 1.2, collisional excitation is the predominant mo

A theoretical analysis is given for the excitation transfer of Xe('P,) +N, (X IX ,') + Xe ( 'SO) + N, (B 'Qy). The analysis is based on (i} pure Coulomb interaction coupled with electron exchange and (ii) spin-dependent interaction between the collision partners. Both mechanisms can account for the

Experimental data on ground- and excited

Experimental data on ground- and excited-state properties for all nuclei with mass number A=144 have been compiled and evaluated. States populated in radioactive decay as well as in nuclear reactions have been considered. For these nuclei, level and decay schemes have been built, as well as tables of nuclear properties. This work supersedes the 1989 evaluation by J.K. Tuli (1989Tu02). Manuscripts published before December 2000 have been included in this work
