外电磁场中光子-轴子转换的总截面

Total cross-section for photon-axion conversions in external electromagnetic field

D. V. Soa, H. N. Long, T. D. Tham

摘要:

我们重新考虑了光子在外电磁场中,即在波导的静态场和周期场中的转换。转换的总截面进行了详细的评估。结果表明,在较强的外电磁场作用下,可以获得足够大的截面来测量轴子的产生。在波导中,在低能量处存在共振转换,其截面值大大增加

英文摘要:

We reconsider the conversion of the photon into axion in the external electromagnetic fields, namely in the static fields and in a periodic field of the wave guide. The total cross-sections for the conversion are evaluated in detail. The result shows that with strong strength of external electromagnetic fields, the cross-sections are large enough to measure the axion production. In the wave guide there exists the resonant conversion at the low energies, in which the value of cross-sections is much enhanced
