Experimental transition probabilities and oscillator strengths of doubly ionised krypton in the ultraviolet region

Producción CientíficaWe report 62 new experimentally obtained transition probabilities (oscillator strengths) for doubly ion- ized krypton within the ultraviolet wavelength region (213 – 362) nm. The transition probabilities were obtained combining measured intensities of spectral lines emitted by a plasma generated in a low- pressure pulsed arc with theoretical oscillator strengths of 12 lines used as a reference. The plasma tem- perature ranged from 26,200 to 29,200 K and the electron density was in the range (1 . 7 −3 . 2) ×10 22 m −3 .Ministry of Education, Science and Technological development of Republic Serbia (grant 451-03-68/2020-14/200125
