Evidence for Δ-h Components from Pion Reactionson the properties of low lying nuclear states is the quenching of the Gamow-Teller strength recently observed in (p,n) reactions.. Because of uncertainties in the Gamow-Teller sum rule this quenching does not lead to direct estimates of the Δ-nucleus admixtures.

Renormalization of Axial β and Magnetic γ Transitions with Δℓ=1 and the Related Giant Resonancesgy E. for the vector mode are found to be consistent with each other, while those for the axial vector mode are inconsistent, in a framework of the spin-iso-spin polarization of the nucleon particle-hole type only. A possible effect of the A nucleon-hole polarization on the axial vector mode is deduced.

Book 1984 The motivation for the conference was, in a large part due to the recent development of new variable energy accelerators which produce high quality beams of electrons, protons, and pions that are providing the first precise information on spin excitations in nuclei over a large range of spin and ma

Models for Pion-Nucleus Reactionsion takes place in the nuclear environment. For pion scattering in the resonance region, the Δ-h formalism has proved to be particularly useful to account for these medium corrections. In the first part of this talk, I shall give a brief summary of the results obtained in applying the Δ-h formalism to elastic pion nucleus scattering.

Charge Exchange Reactions and Spin Modesn correlations in nuclei. The (p,n) reaction for bombarding energies between 100 and 200 MeV has proven to be a unique tool for the study of spin excitations in nuclei. Fig.1 shows zero degree neutron spectra for E.=200 MeV. . The spectra are seen to be dominated by a single peak which is interprete

Observation of M1 Strength in Medium-Heavy Nuclei via the (p,p′) Reaction8 and 9 MeV in most of the nuclei and has a width of around 2 MeV. In all cases, the angular distribution is very sharply forward peaked and is consistent with an orbital angular momentum transfer of zero. The excitation energy, angular distribution and strength of the resonance suggest that it is t

The Experimental Evidence for Gamow-Teller Quenchingbject of discussion for more than a decade.. The question has acquired considerable new interest following the publication of new (p,n) data which allow us to get a view of “complete” GT strength functions.—complete in the sense of covering the excitation energy range containing all states with GT s
