Abstract
The 2+1 black hole anti de Sitter solution, obtained as a special limit of the conformally exact coset WZW model to all orders in 1/k, is investigated with respect to tachyon scattering. We calculate the off-shell reflection and transmission coefficients and we find an expression for the Hawking temperature, which in a certain limit reduces to the statistical result.
