We investigated the negative-parity states and electromagnetic transitions in {sup 151,153}Ho and {sup 151,153}Dy within the framework of the interacting boson fermion model 2 (IBFM-2). Spin assignments for some states with uncertain spin are made based on this calculation. Calculated excitation energies, electromagnetic transitions, and branching ratios are compared with available experimental data and a good agreement is obtained. The model wave functions were used to study {beta} decays from Ho to Dy isotones, and the calculated logft values are close to the experimental data.
