Hyper®ne结构可以对化学丰度的天体物理测定的准确性产生重大影响,并且绝对波数对于线识别和太阳颗粒研究是有用的。我们已经应用共线快离子束激光光谱学来测量Mn ii光谱中73个光学跃迁的hyper®ne结构和hyper® ne-free绝对波数。
Hyper®ne structure can have a signi®cant effect on the accuracy of astrophysical determinations of chemical abundances, and absolute wavenumbers are useful for line identi®cation and solar granulation studies. We have applied collinear fast-ion-beam laser spectroscopy to measure the hyper®ne structures and hyper®ne-free absolute wavenumbers of 73 optical transitions in the spectrum of Mn ii.
