We construct an operator R whose restriction onto weighted pluriharmonic Bergman Space b 2 μ B n is an isometric isomorphism between b 2 μ B n and l # 2 . Furthermore, using the operator R we prove that each Toeplitz operator T a with radial symbols is unitary to the multication operator γ a,μ I. Meanwhile, the Wick function of a Toeplitz operator with radial symbol gives complete information about the operator, providing its spectral decomposition.
