  The experimental thermonuclear reactor, ITER, is currently being constructed
in Cadarache, France. The reactor vessel will be constructred with a beryllium
coated wall, and a tungsten coated divertor. As a plasma-facing component, the
divertor will be under conditions of extreme temperature, resulting in the
sputtering of tungsten impurities into the main body plasma. Modelling and
understanding the potential cooling effects of these impurities requires
detailed collisional-radiative modelling. These models require a wealth of
atomic data for the various atomic species in the plasma. In particular,
partial, final-state resolved dielectronic/radiative recombination (DR/RR) rate
coefficients for tungsten are required. In this manuscript, we present our
calculations of detailed DR/RR rate coefficients for the lanthanide-like, and
low ionization stages of tungsten, spanning charge states W$^{13+}$ to
W$^{1+}$. The calculations presented here constitutes the first detailed
exploration of such low ionization state tungsten ions. We are able to
reproduce the general trend of calculations performed by other authors, but
find significant differences between ours and their DR rate coefficients,
especially at the lowest temperatures considered.
