[en] The present review has five parts which are all self-contained: Theory of giant resonances, The electric giant resonances, Decay of giant resonances, Giant magnetic resonances, Giant Gamow-Teller resonances. A separate abstract was prepared for each of these chapters. Refs, figs and tabs

[en] This paper reports on modern shell-model wave functions that predict relative Gamow-Teller (GT) strengths which agree well with experimental observations. It is essential that both spin-orbit partners of each orbital be included in the model vector space to obtain quantitative theoretical agreement with observations, since the spin-flip aspect of GT operator is dominant. This requirement on vector spaces has the practical effect of limiting quantitative analyses of Gamow-Teller decay with classical shell-model techniques to the p shell and sd shell, with only minor excursions into the fp shell. The authors restrict attention here to the sd shell

[en] The Gamow-Teller strength at high energy, in the vicinity of the pion mass, is linked to the absorption of p wave pions. It is not subject to Pauli blocking and increases linearly with the nucleon number. (orig.)

[en] In this paper, the author would like to discuss what is double beta decay; why there is interest in double beta decay; and what information can be obtained from it

[en] We investigated the distortion effects on the spin transfer coefficient D_nn for the intermediate energy (p,n) charge exchange reactions leading to the Gamow-Teller resonance in the continuum region. When the distortion is included, the imaginary parts of both the central and the tensor direct contributions are significantly changed. Also, the magnitude of T₀₀ becomes smaller, which results in larger D_nn values. We also found that when the distortion is included the phase difference between T₀₀ and T₂₀ in the complex plane remains almost the same for different Q-values

[en] Development of theories of configuration mixing is reviewed, concentrating on their application to spin-isospin modes, especially to the Gamow-Teller transitions. This talk is divided into three historical stages, the first order configuration mixing as the first stage, the second order configuration mixing as the second stage, and the delta-isobar-hole mixing as the third stage

[en] Several recent papers purport to ''test'' the Gamow-Teller sum rule. They compare the differences between incomplete strength function integrals for the β^- and β⁺ directions with the quantity 3(N-Z) and interpret discrepancies as degrees of failure of the sum rule. We point out that the Gamow-Teller sum rule is an exact operator relationship, not a model to be tested. It is useful for determining whether a measured strength function is complete
