  6. The relativistic random phase approximation ( rrpa ) is a relativistic extension of the random phase approximation for studying microscopically nuclear dynamical excitations and giant resonances. the consistency of rrpa calculations requires two aspects : first, it demands that the relativistic mean - field wave " function of nucleus and the particle - hole residual interactions in the rrpa are calculated in a same effective lagrangian. second, the consistent treatment of rrpa within rmf approximation requires the configurations including not only the pairs formed from the occupied fermi states and unoccupied stat es but also the pairs formed from the dirac states and occupied fermi states

    自洽的相對論無規位相近似理論的自洽性要求有兩方面的內容:第一,描述原子核的激發態性質和基態性質時必須從同一個有效的拉矢量出發;第二,相對論無規位相近似計算,不但要考慮正能的粒子-空穴組態的貢獻,而且還要考慮從fermi海核子態到dirac海負能核子態形成的對激發的貢獻。
