The isomeric structure of the N=77 isotones 14265Tb and 14467Ho have been studied with the 92Mo(54Fe, xpn) fusion evaporation reaction at the University of Jyväskylä. The Jurospehere II germanium array was employed in conjunction with the RITU gas filled recoil separator. The feeding and decay of a 500(20) ns isomeric state in 144Ho has been established for the first time together with states built upon the known 15 μs isomer in 142Tb. The behavior of these new structures above the isomers suggest that they are low deformation configurations which display signs of triaxiality.
