类Ne离子中$2p^53s~^3P_2$态辐射的磁场相关角分布和线偏振

摘要:

研究了外磁场对类氖离子$2s^22p^53s~^3P^o_2$态辐射角分布和线偏振的影响。由于B依赖的E1衰变通道被磁场打开并与固有的M2跃迁竞争,角分布和线极化强烈地依赖于磁场强度(B)。作为一个例子,我们说明了在类氖镁的效果。B相关的角分布和线偏振度也可以被认为是诊断等离子体中磁场的工具。

英文摘要:

We studied the effect of an external magnetic field on the angular distributions and the linear polarizations of emissions from the $2s^22p^53s~^3P^o_2$ state in Ne-like ions. Since a B-dependent E1 decay channel is opened by the magnetic field and competes with the inherent M2 transition, the angular distributions and the linear polarizations strongly depend on the magnetic field strength (B). As an example, we illustrated the effect in Ne-like Mg. The B-dependent angular distributions and linear polarization degrees can also be considered as a tool for diagnostics of the magnetic field in plasmas.
