A method for determination of the s orbital component of ~(12)Be ground state

The ambiguity of the structure of ~(12)Be especially in the configuration of Be ground state has attracted a lot of attention recently.We notice that the nuclear reaction cross section or at low energy region is sensitive to the surface structure of ~(12)Be,which is greatly impacted by the ground state configuration of ~(12)Be especially by the occupancy probability of the s orbital component.By using existed interaction cross section data of ~(12)Be on C at 790 MeV/nucleon and Glauber model,the upper limit of the s orbital occupation probability of ~(12)Be ground state is roughly determined to be about 56%with Single Particle Model calculations.This demonstrates that the method is very promising to determine the s orbital component of ~(12)Be with proper nuclear-matter density distribution calculations for different orbitals of ~(12)Be ground state.Hence we bring forward to determine the s orbital component of ~(12)Be by measuring the ctr of ~(12)Be on C and Al at several tens of MeV/nucleon.In this paper,the feasibility and detailed experimental scheme of the ctr measurement are carefully studied.The precision of the s orbital occupation probability of ~(12)Be ground state is expected to achieve 9%by using the proposed 2%ctr data.

浅谈核电站通信系统规划及组成

通信系统是核电站的重要系统之一,它不仅为核电站的日常生产提供基础通信服务和统一授时服务,在事故工况下承担着事故报警、应急指挥和与外界沟通等重要任务。福岛核事故的一个重要经验反馈就是与外界的信息交换不足,造成事故应急处理延误。随着第三代核电站,尤其是AP1000核电站在我国的建设,对核电站通信系统都提出了新的要求。本文依据国家相关法规、AP1000核电站运行标准以及电网的有关规定,对核电站通信系统的建设进行了规划。
