Rotational band in111Sn
Partial level scheme of the neutron deficient111Sn isotope is established upto an excitation energy of about 9 MeV and Iπ=43/2− from γ-rays following103Rh(12C, p3n) reaction. Clear evidence for the existence of a negative parity rotational band aboveγ=23/2−, most probably based on 3p-2h configuration, is obtained.
