giant resonance

Thus, the data confirm the existence of an M1 giant resonance just above threshold in 208Pb.

Initially, studies of isovector monopole and Gamow–Teller giant resonances are planned.

Experimentally these collective modes can be interpreted as special isovector giant resonances in heavy nuclei.

At the lower energies, selective bound state excitation may be studied in photo-production since the giant resonance is kinematically suppressed here.

Giant resonance is a high-frequency collective excitation of atomic nuclei, as a property of many-body quantum systems.

It is shown that the pion angular distributions, in coincidence with the target giant resonance excitations, might provide a well-defined signature for these coherent processes.

In subatomic physics, this is shown for the decay of "giant resonances" in nuclei, where collective nuclear states stand out in otherwise chaotic spectra.

The excitation of multiple giant resonances (i.e., a giant resonance on top of another) in nuclei was also a prediction of his thesis work.

Furthermore, the connection between the origins of the pion distribution to the final pion shapes is made and the importance of the giant resonance in providing an important signature is pointed out.

Measured spin-flip probabilities for combined with a multipole analysis of differential cross sections reveal that at 0°, the apparent continuum under and adjacent to the Gamow–Teller giant resonance is also primarily 1+ strength.

The 90Zr data confirm the recently discovered isovector monopole resonance and provide evidence for two new isovector giant resonances: the spin monopole and the isospin T + 1 component of the quadrupole.

In the macroscopic interpretation of such an excitation in terms of an oscillation, the most prominent giant resonance is a collective oscillation of all protons against all neutrons in a nucleus.

In the (p,n) reaction, the dominant feature at forward angles is the Gamow-Teller giant resonance in all nuclei, and in medium to heavy nuclei, the GT resonance is so prominent that weaker resonances are blocked from view.

A quantal many-body formalism is presented that investigates pion production through the coherent formation of a nucleonic isobar in the projectile and its subsequent decay to various pion charge states along with concomitant excitation of the target to a coherent spin–isospin giant resonance via a peripheral collision of relativistic heavy ions.
