Abstract: | By optical interference and VUV spectroscopy the doublet system of SbI 5p 26s was investigated, so that now the hyperfinestructure of all 8 levels of 5p 26s (A- andB-splitting constants) are known. From the analysis we receive a spin-orbit parameter ζ5p =3,538(57) cm?1 and from the hyperfine-analysis single electron splitting constantsa 5p 01 =52.4(4.6),a 5p 10 =?1.6(7.3),a 5p 12 =72.3(2.3),a 6s 10 =91.7(4.1),b 5p 02 =?49.6(1.1) andb 5p 11 =30.4(3.2) (all values in mK). For all calculations in the fs- and hfs-analysis the 5p 26s 2 D 3/2 has to be excluded (see discussion). With the figures given above the quadrupole moment121 Q(5p 26s)=?0.44(3) barn was obtained. It is in good agreement with the121 Q(5p 3). For the core-polarization by the 5p electron in the innerfieldns-shells (n=1, 2, 3, 4, 5) and the unpaired 6s electron a field of +500(300) kG was obtained. |
