<P><B>Abstract</B></P> <P>We report for the first time two distinctive features in the odd–odd nucleus <SUP>120</SUP>I: a pair of doublet bands and a high-spin isomer built on the π <SUB> h 11 / 2 </SUB> ν <SUB> h 11 / 2 </SUB> configuration. For producing the excited states of <SUP>120</SUP>I, a fusion-evaporation reaction <SUP>118</SUP>Sn(<SUP>6</SUP>Li, 4n) at E = l a b 48 MeV was employed. The beam was provided by the 14UD tandem accelerator of the Heavy Ion Accelerator Facility at the Australian National University. The observed doublet structure built on the positive-parity states is the first case and unique in isotopes with Z = 53 . The emerging properties are indicative of the known chiral characteristics, leading to a doubling of states for the π <SUB> h 11 / 2 </SUB> ν <SUB> h 11 / 2 </SUB> configuration. In contrast, the high-spin isomer with a half-life of 49(2) ns at spin-parity <SUP> J π </SUP> = <SUP> 25 + </SUP> can be explained in terms of a noncollective oblate structure with the full alignment of six valence nucleons outside the <SUP>114</SUP>Sn core: three protons <SUP> ( <SUB> g 7 / 2 </SUB> ) 1 </SUP> <SUP> ( <SUB> d 5 / 2 </SUB> ) 1 </SUP> <SUP> ( <SUB> h 11 / 2 </SUB> ) 1 </SUP> and three neutrons <SUP> ( <SUB> h 11 / 2 </SUB> ) 3 </SUP> . This is an outstanding case that reveals a pure single-particle structure consisting of equal numbers of valence protons and neutrons outside the semi-double shell closure of <SUP>114</SUP>Sn with Z = 50 and N = 64 .</P>
