Electroexcitation of the giant resonance of 17O
… scattering, with special emphasis placed on the giant resonance. The scattering angle employed was 75.1°, and the incident energies were 64.9, 83.3, 101.3, 113.6, and 124.0 MeV. These conditions correspond to momentum transfers in the range 0.33 to 0.77 fm-1. The data reveal a broad resonance …

Photoneutron spectra from monoenergetic photons on Pb208 in the giant resonance
… was smaller than the observed width of the giant resonance by about a factor of 2. This discrepancy and the observed Variation in the direct excess indicated either a breakdown of the assumption of a single dipole state or structure in the statistical width.

Study of transverse excitations in the giant resonance region of 236U using the (e,e'f) reaction.
We measured 236U(e,e'f) coincidence cross sections at six values of the momentum transfer (qeff ~ 0.50, 0.72, 0.84, 0.95, 0.97 and 1.16 fm-1 ) at both forward (Oe = 50°, 75° , 110°) and backward angles (Oe = 160°), over an excitation energy range from 2 to 18 MeV. The backward angle data were taken …

Investigation of the Photoneutron Cross Section in Lead-206 and Lead-208 From 9 to 16 Mev (Photon, Statistical, Decay, Giant Resonance)
The time of flight of photoneutrons from ('206)Pb and ('208)Pb was observed at scattering angles of 55(DEGREES), 90(DEGREES), and 125(DEGREES). Photons with energies between 9 and 16 MeV were used to excite the target nuclei. The incident photon beam was provided by the University of Illinois …
