计算了初级宇宙线与空气核相互作用时产生的高层大气中的p背景。由于p-核和核-核相互作用的p产额不能直接从实验中得知，我们通过使用理论上基于对偶部分子模型并已成功地应用于描述高能碰撞中强子产生的Monte Carlo模拟来获得这些量。计算的大气p背景的结果表明，p背景比以前的估计预测更大，特别是在低能量下。
We calculate the p background in the upper atmosphere which results when primary cosmic rays interact with air nuclei. Since the p yield from p-nucleus and nucleus-nucleus interactions is not directly known from experiments, we derive these quantities by using a Monte Carlo simulation which is theoretically based on the dual parton model and which had been successfully applied to the description of hadron production in high energy collisions. Results on the calculated atmospheric p background indicate a larger p background than earlier estimates predicted, particularly at low energies.© 1996 The American Physical Society.
