$Λ$超核的binding energy的系统研究

A systematic study on the binding energy of $Λ$ hypernuclei

Lan Mi-Xiang, Li Lei, Ning Ping-Zhi

摘要:

本文在统计框架下,用相对论平均场论(RMF)方法系统地计算了$Λ$超核的每重子结合能。实验中发现的大多数超核都具有类似的性质。结果表明,如果一个$Λ$超核是由一个$Λ$超子加到一个稳定的正常核中,或者是由一个$Λ$超子取代一个稳定的正常核中的中子,那么它将是更稳定的.根据我们的计算,在RMF框架下预言了一些新的$Λ$超核的存在。

英文摘要:

In this paper, we calculated the binding energy per baryon of the $Λ$ hypernuclei systemically, using the relativistic mean field theory (RMF) in a statistic frame. Some resemble properties are found among most of the hypernuclei found in experiments. The data show that a $Λ$ hypernucleus will be more stable, if it is composed of a $Λ$ hyperon adding to a stable normal nuclear core, or a $Λ$ hyperon replacing a neutron in a stable normal nuclear core. According to our calculations, existences of some new $Λ$ hypernuclei are predicted under the frame of RMF.
