核子—反核子系跃迁,湮没中的选择定则和湮没截面
摘要
核子和反核子除了可以湮没外
“重子素”束缚态还可能出现束缚态之间的跃迁。这里补充给出了核子
反核子高角动量下跃迁和湮没中的选择定则
其中包括可能产生新粒子J/φ。核子
反核子在高能作用中可“重介子”交换
具体计算了P—P湮没为两个J/φ粒子的微分截面。
Abstract
The antiNucleon--Ncleon system except may annihilate in the motion
The bouud state of Baryonium my also occur transition between different bound states. In this paper
we have given some supplementary yules in the transiton and annihilation of the antiNucleon-Nuclem system at higher angular momentum. Which may produce new particle J/φ in the annihilation process The intera- ction atyhigher energy of the anti Nucleon-Nucleon system can through exchange the heavy meson. We have calculated the differential section when P--P annihilate to two J/φ.
