AV-Ne coupling bound $|g^{\mathrm{A}}_{\mathrm{N}}\,g^{\mathrm{V}}_{\mathrm{e}}|$ against boson mass $Mc^2$/eV, log-log. Solid: constraints from Cs, this work and Ba$^{19}$F; dotted: projected sensitivities of $^{137}$BaF, $^{225}$RaF, Ra$^{19}$F, $^{29}$SiO$^{+}$, Si$^{17}$O$^{+}$; light grey: Combined. Excluded regions, filled in print, are drawn as their boundary lines.
