摘要 研究了一个改进的Skyrme模型,在重子数守恒的新的标度变换下,同时考虑孤立子的转动与振动耦合,通过最低阶半经典近似处理,推出了包括振动与转动耦合在内的与标度参数有关的孤立子哈密顿,由N、Δ能级分裂公式推出了理论参数fπ和m,并且计算了核子的静态性质.计算结果与原先的Skyrme模型的预言相比,绝大部分数据有了改进,其结果基本符合于实验值. We studied a modified Skyrme model. At the same time, we have considered (rotational)-vibrational coulping under the new baryon-number-preserving scaling transformation. The soliton hamiltonian with rotational-vibrational coulping about to scaling was deduced by the limitations of a semiclassical approximation. Then, the nucleon-Δ energy level split formula was obtained and the theoretical parameters f_π,m were fixed. Our results that the static properties of nucleons compared to that Skyrme have predicted that the most of the oretical values were improved and closed to experimental value.
