Total Maxwellian-averaged DR and RR ground-state rate coefficients for Fe¹²⁺: a) black solid curve, previous recommended data of Mazzotta et al. (1998); b) green dashed curve, present MCBP results; c) blue dotted curve, empirical formula of Mewe et al. (1980); d) magenta dotted-dashed curve, present RR rate coefficient; e) red dotted-dashed curve, previous MCBP results presented in Hahn et al. (2014); and f) black dashed curve, experimental measurements (Hahn et al. 2014).
