摘要
针对轴对称形变原子核系统,提出在柱坐标空间计算介子场与库仑场传播子的新公式,并在柱坐标空间直接求解介子场与库仑场。在相对论平均场近似框架下,柱坐标空间直接计算介子场与光子场的方法精确再现了原有谐振子基展开方法的计算结果,包括球形幻数原子核与形变的^(148-160)Nd偶-偶同位素的结合能、均方根半径、四极形变β及介子场与库仑场对能量泛函的贡献,验证了柱坐标空间计算介子场与库仑场传播子公式的正确性。
Aiming at axial deformed nuclear systems,a new formalism of the meson and photon propagators was presented in cylinder coordinate space,and the meson and photon mean fields were calculated directly.Under the frame of the relativistic mean field approach,the new proposed algorithm of propagators reproduces exactly the calculation by the oscillator basis expansion method,including the binding energy,root-mean-square radii,quadrupole deformation and the contributions to the energy functional from meson and photon fields for the spherical magic nuclei and well-deformed ^（148-160）Nd isotopes.The result verifies the reliability of the new technique for calculation of propagators in cylinder coordinate space.
