银河系弥散γ射线计算中的核增强因子:用DPMJET-3的新估计

Nuclear enhancement factor in calculation of Galactic diffuse gamma-rays: A new estimate with DPMJET-3

Masaki Mori

摘要:

本文利用蒙特卡罗模拟器DPMJET-3,提出了一种新的核增强因子计算方法,用于从质子-质子相互作用中估算银河系弥散γ射线通量,以考虑宇宙射线和星际物质中的重核。在6-1000 GeV/核子的能量范围内,一个新的值为1.8-2.0,随着发射宇宙射线的动能的增加而略有增加,比以前的估计大了大约20%。

英文摘要:

A new calculation of nuclear enhancement factor, used in estimation of Galactic diffuse gamma-ray flux from proton-proton interaction in order to take account of heavy nuclei included in cosmic-rays and interstellar matter, is presented by use of a Monte Carlo simulator, DPMJET-3. A new value of 1.8-2.0 in the energy range of 6-1000 GeV/nucleon, slightly increasing with kinetic energy of projectile cosmic rays, is about 20% larger than previous estimates.
