核物质中的核子、介子和Δ共振态

Nucleon,Mesons and Deltas in Nuclear Matter

在相对论D B近似的框架内 ,构造了两个单玻色子交换OBE(OneBosonExchange)势 ,一个只包含核子 ,另一个还包含Δ自由度 ,在完备的动量—自旋空间中计算了 (N ,N)和 (N ,Δ)系统的所有t矩阵和自能 。

Within the framework of the relativistic Dirac Brueckner approach,the paper constructs two one boson exchange(OBE) interactions,one for nucleons only,the other including Δ degrees of freedom,calculates all t matrices and Δ self energy in the (N,N) and ( N,Δ ) systems in the full momentum spin space,and obtains better results.
