Summary
It is shown that the concept of seniority can be introduced in projection operator formalism through the use of the operatorQ, which has been defined by de-Shalit and Talmi. The usefulness of seniority concept in projection operator formalism is discussed. An example of four nucleons inj=3/2 configuration is given for illustrative purposes.
Riassunto
Si dimostra che il concetto di anzianità si può introdurre nel formalismo dell’operatore di proiezione attraverso l’uso dell’operatoreQ, che è stato definito da de-Shalit e Talmi. Si discute l’utilità del concetto di anzianità nel formalismo dell’operatore di proiezione. Si dà a scopo illustrativo un esempio di quattro nucleoni nella configurazionej=3/2.
