摘要
根据蟹状星云中γ射线的观测数据拟食谱,对γ射线的辐射机制进行了分析.通过同步加速吸收的加速机制使电子得到产生γ射线的能量,定性确定了辐射γ射线的电子能量的上限.由观测谱推断高能γ射线是逆康普顿散射机制产生的,并由此确定了不同能量段的γ射线发自星云不同的区城。
According to observed Gamma- ray fit spectrum, Gamma -ray emission mechanism is analyzed. The upper limit of electron energy that causes Gamma-ray emission is determined. The electrons obtain energy from synchrotron absorption acceleration. The conclusion is that high energy Gamma-ray is the result of inverse-Compton scattering, and Gamma-rays with different energies radiate from different regions in the crab nebula.
