Abstract

A Fermi-aligned (i_{13 2})² rotational band, with K≈8, has been observed in an even-even nucleus, ¹⁸⁰W. Its structure corresponds to a t-band in the tilted-cranking representation. It crosses the ground-state band at I = 16 h {combining short stroke overlay}, giving rise to backbending in the yrast sequence. Contrary to the usual interpretation, backbending in this case is not caused by the s-band. Comparison is made with other possible t-band crossings in the A ≈ 180 region.
