论文摘要
在Helmholtz-Zentrum Berlin的质子治疗中心,在E_ALPHA = 50-90 MeV的范围内测量了在alpha粒子反应中产生的最强伽马射线发射线的横截面。确定了60多种不同的伽马射线线的数据,并针对横截面汇编/带有天体物理目的评估以及在较低的弹丸能量中存在的数据进行了特殊的努力。将数据与现代核反应法规的预测和太阳耀斑加速粒子相互作用中伽马射线发射的最新评估的横截面曲线进行了比较。
Cross sections for the strongest gamma-ray emission lines produced in alpha-particle reactions with C, Mg, Si, Fe have been measured in the range E_alpha = 50 - 90 MeV at the center for proton therapy at the Helmholtz-Zentrum Berlin. Data for more than 60 different gamma-ray lines were determined, with particular efforts for lines that are in cross section compilations/evaluations with astrophysical purpose, and where data exist at lower projectile energies. The data are compared with predictions of a modern nuclear reaction code and cross-section curves of the latest evaluation for gamma-ray line emission in accelerated-particle interactions in solar flares.
