Abstract

The cross section of the isovector giant dipole resonance (GDR) excited by inelastic scattering of 120-MeV alpha particles for 0-degrees less-than-or-equal-to THETA-alpha' less-than-or-equal-to 3-degrees has been measured using the Sn-116,124(alpha,alpha'gamma-0) and Pb-208(alpha,alpha'gamma-0) reactions. The results are compared with distorted-wave Born-approximation calculations with a GDR form factor depending on the relative difference of proton and neutron radii (DELTA-R(pn)/R0). Within the model used, the DELTA-R(pn)/R0 values for Sn-116, Sn-124, and Pb-208 deduced from the comparison of measured and calculated cross sections are (0.7 +/- 0.7(2.3)%, (4.1 +/- 2.5(2.1)%, and (3.0 +/- 1.3)%, respectively.
