  Rate coefficients for the dissociative recombination, vibrational excitation
and vibrational de-excitation of the BeT$^{+}$ ion for all vibrational levels
of its ground electronic state ($
X\ensuremath{^{1}\Sigma^{+}},v_{i}^{+}=0,\dots,27$) are reported, including in
the calculation the contribution of super-excited states of the BeT complex
pertaining to three electronic symmetries - $^{2}\Pi$, $^{2}\Sigma^{+}$, and
$^{2}\Delta$. These data are suitable for the kinetic modeling of beryllium and
tritium containing plasma, as encountered in magnetic fusion devices with
beryllium walls (JET, ITER). In the present study we restrict ourselves to
incident electron energies from 10$^{-3}$ up to $2.7$ eV, and to electron
temperatures between $100$ and $5000$ K, respectively. Together with our
earlier and closely related studies on the BeH$^{+}$ and BeD$^{+}$ systems,
this present work completes the isotopic coverage for the beryllium monohydride
ions. The vibrational energy (rather than the vibrational quantum state) is
identified as a proper isotopic similarity parameter, e.g., for reduced but
still isotopically correct plasma chemistry models.
