From: Production study of Fr, Ra and Ac radioactive ion beams at ISOLDE, CERN
Release curves for Ac, Ra and Fr at 2000 \(^\circ\)C. (a) Saturation of \(^{227}\)Ac production (proton beam On). Data obtained as ion current on FC. (b) Release of \(^{227}\)Ac, proton beam Off after saturation. Data obtained as ion current on FC. (c) Release curve of \(^{214}\)Ra. Data obtained as \(\alpha\) particles evolution in time. (d) Release curve of \(^{205}\)Fr. Data obtained as \(\alpha\) particles evolution in time. The blue vertical line represent the proton pulse. The red line represents the fit according to Eq. (1).
