We study a nonminimal massive scalar field in a 2-dimensional black hole spacetime. We consider the black hole which is the solution of the 2d dilaton gravity derived from string-theoretical models. We found an explicit solution in a closed form for all modes and the Green function of the scalar field with an arbitrary mass and a nonminimal coupling to the curvature. Greybody factors, the Hawking radiation, and $ < \phi^2 >^{ren} $ are calculated explicitly for this exactly solvable model.

Then, for arbitrary $a>0$ in the metric ([ref]) the Euclidean Green function can be written in terms of the Legendre function exactly as for CGHS black hole case (see [ref] ) G_E G_E(X,X') = -14sin(πν) P_ν(-λ), where λ = (1-2z)(1-2z')+4√(zz'(1-z)(1-z'))cos(τ-τ'2) lambda = cosθcosθ'+sinθsinθ'cos(φ-φ').
