Summary

Dynamical-correlation effects are studied in relation to both elastic and inelastic electron scattering processes, using a sum rule approach. The role of tensor correlations turns out to be important especially in spin-isospin modes. Detailed results are presented for16O showing the different influence of tensor correlations in longitudinal and transverse spin-isospin excitations.

Riassunto

Si studiano gli effetti delle correlazioni dinamiche in processi, elastici ed inelastici, di diffusione di elettroni, mediante un approccio con regole di somma. L’importanza delle correlazioni tensoriali si evidenzia specialmente nei modi di spin-isospin. Risultati dettagliati nel caso del16O mostrano una diversa influenza delle correlazioni tensoriali nei due tipi di eccitazione, longitudinali e trasverse, di spin-isospin.

Резюме

Исследуются динамические корреляционные эффекты в процессах упругого и неупругого рассеяния электронов, используя подход правил сумм. Указывается, что роль тензорных корреляций является важной, особенно в спин-изоспиновых модах. Приводятся результаты для16О, показывающие различное влияие тензорных корреляций на продольные и поперечные спин-изоспиновые возбуждения.
