Nickel-Like Samarium 4d-4p X-Ray Laser Gain in Laser Plasmas
Abstract
Populations of the 249 levels belonging to the ground configuration 3s23p63d10 and those of single excitations of a 3d,3p or 3s electron to the orbitals of n = 4 and 5 have been calculated for nickel-like samarium at temperatures from 300 to 1600 eV and at densities from 1020 to 1022 cm-3. The gain coefficients for possible x-ray laser lines are also determined under these plasma conditions. The possible laser lines are transitions from levels (3d3/2-14d3/2)0 and (3d5/2-14d5/2)0 to levels (3d3/2-14p1/2)1, (3d5/2-14p3/2)1 and (3d3/2-14p3/2)1. The favourable plasma condition for x-ray lasers is at the temperature of about 800 eV and at the density of approximately 5.0×1021 cm-3.
