反质子与原子核的电荷交换反应

Antiproton-nucleus change exchange reaction

本文研究在扭曲波冲量近似下，反质子与原子核的电荷交换反应Ａ（ｐ，ｎ）Ｂ．用严格的分波法计算反质子能量为４６．８ＭｅＶ和１７９．７ＭｅＶ的１６Ｏ（ｐ－，ｎ－）１６Ｎ到达１－，３－态和１７Ｆ（ｐ－，ｎ－）１７Ｏ到达Ｏ＋，２＋态的微分截面．讨论了同位旋相似态跃迁和非相似态跃迁微分截面的差别．

In this paper is studied the antiproton-nucleus charge exchange reaction A (p-, n) B under the distorted wave impulse approximation. By using the exact partial wave calculation, the differential cross section of 16O (p-, n-)16N 1-, 3- states and 17F (p-, n)17O0+, 2- states at antiproton energies of 46. 8 MeV and 179. 7 MeV are calculated. Also, the differences in differential cross section between the analogous states transition and inanalogous states transition are discussed.
