Abstract

To investigate the spectator role of the d5/2 unpaired proton outside the Z=50 closed shell, the ¹²⁰Sn(p,α) ¹¹⁷In and ¹²¹Sb(p,α)¹¹⁸ Sn reactions have been measured in high resolution experiments, performed with the 23 MeV proton beam of the Munich MP Tandem, using the Stern-Gerlach type polarized hydrogen ion source and the Q3D magnetic spectrograph.
