| 摘 要： | 共振逆康普顿散射(RICS)已被证明在典型的脉冲星表面温度和磁场条件下,是次级粒子(洛仑兹因子低于104)主要的能量损失机制.次级粒子的分布函数也会因为共振逆康普顿而改变.文章重新计算了次级粒子最后稳定分布函数,并修正了Lyubarskii和Petrova(2000)一文中分布函数结果不满足次级粒子数目守恒的假设.就此结果在解释脉冲星射电谱拐折现象中的应用进行了讨论.

| Abstract: | It has been demonstrated that resonant inverse Compton scattering (RICS) can be the dominant mechanism in the energy loss of secondary particles with γ<104 in pulsar magnetosphere under typical surface temperature and magnetic field. The distribution function of secondary particles will be changed due to RICS. We recalculate the ultimate distribution function of secondary particles and correct the error presented in Lyubarskii & Petrova (2000), in which the results are not consistent with the assumption of conservation of particle number. The possible implication to explain the break of pulsar radio spectrum is discussed. |
