| 摘 要： | 使用两个跃迁频率,观测W33B的OH分子左右圆偏振的脉泽辐射.从左右圆偏振谱的Zeeman速度分裂,导得脉泽活动区的磁场大约为5mG.采用均匀抽运,完全饱和辐射的球模型,估计脉泽活动区的原恒星物质的氢分子数密度为3×107cm-3.

| Abstract: | The polarization observations are carried out towards OH masers in W33B with the 2Ⅱ3/2, J = 3/2, F=1→1, and F = 2→2 transitions. The magnetic strength of 5 mGis inferred by the Zeeman splitting between right and left circular polarization spectra. The hydrogen density of the protostellar matter, n(H2) =3×107cm-3, in the active massing region is estimated by considering a spherical maser with the fully saturation and the homogeneous pumping. |
