In extending the CVTS model to relativistic energies, Haque et al. [48] incorporated in their XCVTS model a Gryzniski-type [22] relativistic factor R(U) given by... 

The relativistic parameters Si, S2, and S3 in Eq. (10), the ionic parameters f and r) in Eq. (11), and the parameters Q and in Eq. (12) have been optimized by minimizing the chi-square, shown in Eq. (8), for fitting the experimental data with the criteria specified earlier. The optimization procedure is similar to that followed for the MBELL model excepting that the repetition over the number of targets is to be done for the same ionizing shell in place of orbit for seeking the convergence of the parameter values. The optimum values thus obtained for all parameters of the XCVTS model are tabulated in Table 6.2. 

The XCVTS model is simulation of DWBA calculations, through its parent CVTS [47] model, in terms of the two fitting parameters Q and X shown in Eq. (12) apart from other shell-independent parameters depicted in Table 6.2. 

The calculated EISICS from the MBELL, XCVTS, GKLV, and MUIBED models are compared with available experimental data the K-shell ionization...
