Abstract:	The ¹²⁸Te(³⁵Cl, 5n) reaction has been used to study the Yrast band in ¹⁵⁸Tm to populate to high spin states (up to I = 27). The BC backbending has been observed and the $[i 132]$ neutron subshell is, by the way, definitely confirmed to be a component of the Yrast band. An experimental value of the residual proton-neutron interaction is deduced $(V ? ?0.160 MeV$ .
