Spectroscopic factors of negative-parity multiplet states in odd Sn isotopes

The spectroscopic factors of the negative-parity multiplet states 7 2 − 1 , 9 2 − 1 , 11 2 − 2 , 13 2 − 1 and 15 2 − 1 in odd Sn isotopes are calculated by including leading-order scattering and ground-state correlation processes. It is shown that ground-state correlations play an important role for the spectroscopic factors of the 7 2 − 1 and 11 − 2 states. The theoretical results are in good agreement with the available experimental data.
