The giant electric dipole resonance built upon the 0/sup +/ ground state of /sup 20/Ne was studied via the /sup 19/F(p-arrow-right,..gamma../sub 0/)/sup 20/Ne reaction. Polarized and unpolarized angular distributions were measured between E/sub x/ = 16.1 and 23.0 MeV (E/sub p/ = 3--10 MeV) and the E1 T-matrix elements extracted. The /sup 1/P, E1 partial wave dominates, but the weaker /sup 3/P (spin flip) term is also resonant. A heuristic doorway state model has been used to fit the pronounced structure in the giant E1 resonance. Data for the giant resonance built on the first excited state as seen in the /sup 19/F(p-arrow-right,..gamma../sub 1/)/sup 20/Ne reaction are presented and discussed. The microscopic, doorway state calculation in a deformed potential of Schmid and Do Dang is in very good agreement with the main features of the results.
