$1^+$ hallerin taban hal korelasyonlarına etkisi

Taban haldeki kuaziparçacık sayısı ile ölçülebilen taban hal korelasyonları (GSC), Rasgele Faz Yaklaşımı (QRPA), Renormalize QRPA (R-QRPA) ve Tamamen Renormalize QRPA (FR-QRPA) yaklaşımlarndaki Hamiltoniyenler ele alınarak çalışıldı. Hesaplama sonuçları, GSC de yüksek enerjili $1^+$ hallerin önemini ve teorinin güvenirliliği için RPA çözümlerinin tam çözümlerinin ne derece önemli olduğunu gösterdi.

The ground state correlations (GSC) measured by the number of quasiparticles in the ground state are studied for the Hamiltonian within the Random Phase Approximation (QRPA), the Renormalize QRPA (R-QRPA) and the Fully Renormalized QRPA (FR-QRPA) approaches. The result of calculations has indicated a significant role of the high energy $1^+$ states and the importance to use full complete set of the RPA solutions for reliable predictions of the theory in GSC.
