Query: $\beta$-decay rates of $^{(115,117)}$Rh into $^{(115,117)}$Pd isotopes
  in the microscopic IBFM-2   The structure of odd-$A$ $^{(115,117)}$Rh and $^{(115,117)}$Pd isotopes is
studied by means of the neutron-proton Interacting Boson-Fermion Model
(IBFM-2). $J^P = \frac{1}{2}^+$ quantum number assignment for the
$^{(115,117)}$Pd ground-states is critically discussed and the predicted energy
levels are compared to the existing experimental data. The resulting nuclear
wave functions are used to compute the $\beta$-decay $ft$ values of the
transitions from $^{(115,117)}$Rh to $^{(115,117)}$Pd in the microscopic IBFM-2
and the results compared with the data.
