 On the connection between continuous Hahn
polynomials and the Heisenberg algebra
(14K, latex)

ABSTRACT.   We give an elementary proof for the connection between a system
 of continuous Hahn polynomials and symmetrizations of elements 
  in the Heisenberg algebra (Bender, Mead and Pinsky 1986, 1987;
 Koornwinder 1989).
