<正> By means of an improved ligand-field theory,the'pure electronic' PS and the PS due to EPI of R line ofMgO:V~(2+) have been calculated,respectively.
<正> Using the integral representation of the Jost solution,we deduce some conditions as the kernel functionN(x,y,t)if the Jost solution satisfies the two Lax e
