标题： New local interstellar spectra for protons, Helium and Carbon derived from PAMELA and Voyager 1 observations

摘要： 借助旅行者1号航天器在日球层主导调制影响之外的宇宙射线观测，终于可以将计算出的银河宇宙射线能谱与较低能量下的实验数据进行比较。 现在，可以使用银河宇宙射线传播模型，将专门针对质子、氦核和碳核的能谱与旅行者1号在低能区的观测值以及PAMELA空间探测器在地球附近的高能区观测值进行比较。 我们旨在利用GALPROP代码重现旅行者1号在6 MeV/核子到60 MeV/核子能量范围内的观测值，并重现PAMELA在高于50 GeV/核子处的能谱，这与我们之前关于旅行者1号电子的研究类似。 通过改变GALPROP纯扩散模型中的银河宇宙射线扩散参数，特别是空间扩散对刚度的依赖性，并加入再加速效应，我们同时计算了银河系质子、氦核和碳核的能谱。我们提出了新的局部星际空间能谱，其适用于3 MeV/核子至100 GeV/核子的能量范围，这对太阳风调制建模具有一定的价值。 显示英文摘要

摘要： With the cosmic ray observations made by the Voyager 1 spacecraft outside the dominant modulating influence of the heliosphere, the comparison of computed galactic spectra with experimental data at lower energies is finally possible. Spectra for specifically protons, Helium and Carbon nuclei, computed by galactic propagation models, can now be compared with observations at low energies from Voyager 1 and at high energies from the PAMELA space detector at Earth. We set out to reproduce the Voyager 1 observations in the energy range of 6 MeV/nuc to 60 MeV/nuc, and the PAMELA spectrum above 50 GeV/nuc, using the GALPROP code, similarly to our previous study for Voyager 1 electrons. By varying the galactic diffusion parameters in the GALPROP plain diffusion model, specifically the rigidity dependence of spatial diffusion, and then including reacceleration, we compute spectra simultaneously for galactic protons, Helium and Carbon.We present new local interstellar spectra, with expressions for the energy range of 3 MeV/nuc to 100 GeV/nuc, which should be of value for solar modulation modeling.
