Differential cross-sections for secondary antiproton and antideuteron production

We present the differential cross-sections for secondary antiproton and antideuteron production. Each file is associated to different production processes: p+H, p+He, He+H, He+He, where the first particle designates the cosmic-ray projectile and the second particle the target nucleus in the interstellar medium. Each file contains 6 columns. The two first report the kinetic energy per nucleon (in GeV/n) of the projectile and of the produced antinucleus. The third column reports the associated differential cross-section for antiprotons production (in m2/GeV). The remaining columns report the differential cross-sections for antideuteron production (in m2/(GeV/n)) using different coalescence models (see more details in the associated publication). The range for kinetic energies per nucleon of the projectile is from ~15 GeV (energy threshold for secondary antideuteron production and coincidently the lowest energy threshold allowed by PYTHIA) to 10 PeV. While the range for kinetic energies per nucleon of the produced antinucleus is from 0.1 GeV to 10 TeV. Both ranges are logarithmically spaced with 100 points.本数据集提供次级反质子（antiproton）与反氘核（antideuteron）产生的微分截面（differential cross-section）数据。每个文件对应一组特定的碰撞产生过程：p+H、p+He、He+H、He+He，其中第一项粒子为宇宙线入射粒子，第二项为星际介质中的靶核。 每个文件包含6列数据。前两列分别给出入射粒子与生成反核的每核子动能（单位：GeV/n）。第三列为反质子产生对应的微分截面（单位：m²/GeV）。剩余列给出采用不同聚结模型（coalescence models）时反氘核产生的微分截面（单位：m²/(GeV/n)），详细说明可参见相关发表文献。 入射粒子的每核子动能范围约为15 GeV（该值为次级反氘核产生的能量阈值，同时也是PYTHIA程序允许的最低能量阈值）至10 PeV。生成反核的每核子动能范围为0.1 GeV至10 TeV。两类动能范围均采用对数间距划分，各包含100个数据点。
