Partial level scheme of the neutron deficient Sn-111 isotope is establ
ished upto an excitation energy of about 9 MeV and I(pi) = 43/2- from
gamma-rays following Rh-103(C-12,p3n) reaction. Clear evidence for the
existence of a negative parity rotational band above I(pi) = 23/2-, m
ost probably based on 3p-2h configuration, is obtained.
