The Sn isotopes belong in the nuclear structure physics to the most important representatives of the nucleon-nucleon interaction and the resulting shell structures. A total number of 10 stable isotopes demonstrates the unique power of stability of the magic proton number Z=50. Systematic measurements of the E2 transition strengths and the magnetic moments of the 21+ states of all stable isotopes indicate that the nuclear structure is more complicated than one would expect on the basis of extensive shell model calculations. This feature is particularly expressed by the measured enhanced B(E2) values of the neutron-deficient 106,108,110Sn isotopes as well by the minimum recently found for 116Sn. In view of these data we are planning to measure the g-factor of 110Sn(21+) in order to obtain more insight into the nucleon structure of this nucleus.
