Summary
Isotopio spin formalism is introduced in first and second K.P.A. A simple calculation of the levels 2+ T=0 and 4+ T=0 of28Si is performed. The application of first K.P.A. gives results in agreement with the values obtained by a shell-model calculation. The introduction of double excitations of the type particle-hole do not affect appreciably our results.
Riassunto
Si introduce lo spin isotopioo nel formalismo délia prima e seconda E.P.A. Si fa nna semplice applicazione al calcolo dei Iivelli 2+ T=0 e 4+ T=0 nel caso del28Si. Mediante la prima R..P.A. si ottengono risultati simili a quelli ottenuti con il modello a « shell ». L’introduzione di eccitazioni doppie del tipo particella-lacuna non altéra sensibilmente i risultati.
