包含介子自由度的相对论Hartree近似的质心修正

Center-of-Mass Correction in a Relativistic Hartree Approximation Including the Meson Degrees of Freedom

P. Alberto, S. S. Avancini, M. Fiolhais, J. R. Marinelli

摘要:

用Peierls-Yoccoz投影方法研究了相对论性核子与σ、ω介子相互作用系统的运动。用平均场Hartree方法描述了该核系统,明确地考虑了介子的贡献,并将该方法应用于一些选定的N=Z球形核.的质心运动校正使系统太多有界,但我们表明,适当的改装模型带来的半径和结合能接近实验值。

英文摘要:

The Peierls-Yoccoz projection method is used to study the motion of a relativistic system of nucleons interacting with sigma and omega mesons. The nuclear system is described in a mean-field Hartree approach, including explicitly the meson contribution and the formalism is applied to some selected N=Z spherical nuclei. The center-of-mass motion correction makes the system too much bounded, but we show that an appropriate refitting of the model brings the radii and binding energies close to the experimental values.
