Nuclear charge radii of the Te isotopes from muonic atoms
The muonic atom energies of the 2p-1s and the 3d-2p transitions were measured with a statistical accuracy of better than +- 70 and +- 40 eV, respectively, for /sup 123,124,125,126,128,130/Te. The values for the Barrett equivalent nuclear radii R/sub k//sub ,//sub ..cap alpha../ and for the root-mean-square radii and their differences were calculated first from muonic data alone and second with the addition of published optical data. The latter data provided the radii of /sup 120/Te and /sup 122/Te isotopes, which were not measured by muonic x rays. A combined analysis of the muonic atom and optical isotope shift data yielded high-precision values of the differences in radii ..delta..R/sub k//sub ,//sub ..cap alpha../ (error < +- 0.5 am) and ..delta../sup 1/2/ (error < +- 0.9 am) between the neighboring isotopes. The optical constants for the Te line lambda = 4049 A were determined (including contributions of higher radial moments) to be F = (509 +- 120) mK/fm/sup 2/ and M = -(104 +- 63) x 10/sup 3/ mK. Systematic behavior of the radius differences in neighboring isotopes and isotones of Ba, Xe, Te, and Sn, together with odd-even staggering of the Te isotopes, are discussed in this paper. The ..delta..N = 2 Te isotope shifts between even-A nuclei decrease nearly linearly with increasing N, which can be explained by a successive decreasing deformation in accordance with the observed systematics.
