| Research Abstract |
Around nucleus of which the number of protons and neutrons are the "magic number", the nuclear stability increases very well. In such nuclei, we can find the higher order effects in the nuclear structure. So far such study has been done around stable nuclear region; we apply it to neutron-rich region. We measured the magnetic moment of unstable nuclei 49Sc (T1/2 = 57m) by the on-line nuclear orientation method. We compared the result with recent nuclear theoretical calculations. The calculations agree with our results but it shows a need for improvement in theoretical calculation around stable doubly closed shell nuclei.
