“…The 32S spectrum, however, reveals more structure than the lvO spectrum. The authors conjectured [20] this fact to be caused by excitations of states in the projectile, and 170 has many fewer particle stable states than 31S. This suggestion is fully in line with our supposition that mutual excitation of target and projectile is predominant and is likely to cover any signature due to pure target excitations.…”

“…A recent study [20] of the high energy nuclear continuum in 2~ excited by 22 MeV/u 170 and 32S showed clearly that the excitation strength of the isoscalar giant quadrupole resonance at 10.6 MeV depends strongly on the projectile: it is prominent in the case of 170 but by far less pronounced in that of 32S. The 32S spectrum, however, reveals more structure than the lvO spectrum.…”

Angular distributions for inelastic scattering, for 1 and 2-nucleon transfer reactions were studied at 18.2 MeV/u beam energy. Owing to sequential decay of excited reaction products the nuclide yield measured at various angles and in different regions of total kinetic energy loss (TKEL) does not represent the yield of primordial nuclides AZ. Monte Carlo calculations were applied in order to reconstruct the primary double-differential cross-sections d2a/dcodTKEL for values of TKEL up to 80 MeV. By comparing the probability of inelastic scattering and that of transfer reactions it is found that the former dominates for TKEL < 10 MeV, whereas the situation is reversed above 20 MeV. No evidence is found for the excitation of giant resonances with significant cross section.Nuclear Reactions: measured d 2 a/d o) dTKEL for z o 8pb + 86Kr at 18.2 MeV/u; unambiguous nuclide identification by magnetic spectrometer; primary TKEL spectra reconstructed by means of Monte Carlo calculations; angular distributions deduced for inelastic scattering, l n, 2n and lp-transfer; comparison of probabilities for inelastic excitation and nucleon transfer.

“…The existence of such exotic large-amplitude collective states in nuclei has yet to be experimentally verified even though a fairly large body of data has been collected [1 -9]. We note, though, an indication of the excitation of double GDR states in pion double charge exchange reactions [10], and an interpretation of high energy structures in the excitation energy spectra in zosPb targets following inelastic collisions with various projectiles in terms of multiphonon excitations [11], although these structures were not reproduced in subsequent measurements [12]. Very little is known from an experimental or theoretical perspective concerning the decay of multiple GDR states.…”

Conditions optimum for the first experimental verification of the multiple electromagnetic excitations of nuclei in relativistic nucleus-nucleus collisions are described. The relative magnitudes of three important physical processes that might interfere with such a measurement are compared to the predicted strengths for the single and multiple electromagnetic excitations for various choices of the projectile mass and beam energy. Strategies are presented for making inferences concerning the presence of multiple excitation strength in experimental data. PACS number(s): 25.75.+r 45 799

“…Excitation-energy spectra obtained from inclusive measurements using such projectiles as Ar or Ne, in fact, indicated structures that were tentatively assigned to multiphonon quadrupole resonances (63) (and references therein). The structures, however, were superimposed on a large background and thus were in dispute (64). More exclusive experiments were required in order to clarify the situation.…”

We review the present knowledge of multiphonon giant resonances in nuclei. Theoretical concepts approaching the intrinsic structure and excitation mechanisms of multiphonon states are discussed. The available experimental results are summarized, including a brief description of applied techniques. This review emphasizes electromagnetic excitations of double dipole resonances. Open questions and possible routes toward a solution are addressed.
