Abstract
In this paper, the effect of magnetic field (1.1Â T) on the atomic and ionic spectral emission of a laser produced lithium plasma at low pressure has been investigated. The experimental results indicate that magnetic field enhances the intensities of lithium atomic spectral lines but reduces the ionic spectral lines intensities. Fig. 1 shows the temporal resolved images of laser produced Li ions and atoms plasma plume in the presence and absence of magnetic field. The plasma dynamic images show that with the magnetic field, the number density of luminous Li atoms is higher, while the number density of luminous Li ions is lower in comparison to the field-free case.216
