低能区π-^(14)C和π-^(18)O双电荷交换反应分析

Analysis of π－^（14）C and π－^（18）O DCX Reaction at Low Energies

应用Glauber理论对14C（π+，π-）14O和18O（π+，π-）18NeDCX反应在Tπ＝50MeV处的微分截面进行计算。核波函数假定由2价核子和3α核心（对于14C）或4α核心（对于18O）组成。结果表明，理论值与实验值符合得很好。

The π-14C and π-18O cross section at 50 MeV is calculated with the Glaubertheory. The nuclear wave function is assumed to be constructed by two vallence nucleonsplus a core of three a-particles (for 14C) or four α-particles (for 18O). A good agreementbetween theory and experiments is obtained.
