High resolution spectroscopy of pionic-atom with Sn isotopes
Abstract
We will report the result of the high resolution spectroscopy of pionic-atom with Sn isotopes which was performed in this spring as a further study of our deeply bound pionic atom states experiment with Pb isotopes. This experiment was done at FRS in GSI running it as a high resolution spectrometer. The experimental goal is to measure binding energies and widths of pionic 1s states widely along Sn isotope chain with high accuracy. We observed clear peaks in the excitation energy spectrum via Sn(d,^3He) reaction at T_d=500MeV. The precise information on pionic 1s-state binding energies and widths in Sn nuclei and their isotope dependence effectively works to limits existing optical potential parameters. The determined potential will also be translated to the effective pion mass in nuclear matter.
