Isotopic differences of charge distributions of even isotopes of tin
Isotopic variation of rms charge radii of even isotopes of tin (112–124) has been calculated on the basis of an average one body potential. The potential parameters were optimized in the lead region after taking the effect of core polarisation into consideration. The optimized potential parameters were then interpolated in the tin region. Single particle (-hole) energies along with the orbit radius have also been calculated. Comparison with experimental results show very good agreement. The calculated charge distributions after the usual corrections were subjected to model independent Fourier-Bessel analysis from where Fourier-Bessel coefficients have been extracted. Results of rms charge radii show that this phenomenological approach gives a very good description of the experimental situation.
