The low-lying, low-spin levels of $^{141}\mathrm{Pr}$ were investigated using ($n,{n}^{'}\ensuremath{\gamma}$) techniques. Level energies, branching ratios, and tentative spin assignments for more than 100 states, linked by nearly 300 transitions, were obtained from two angular distributions (${E}_{n}=2.0$ and 3.0 MeV) and an excitation function measurement (${E}_{n}=1.5\text{\ensuremath{-}}3.2$ MeV). The application of the Doppler-shift attenuation method led to the determination of lifetimes. The obtained spectroscopic data provide insight into the wave functions of the states observed. A detailed analysis of the $[{2}_{1}^{+}\ensuremath{\bigotimes}{d}_{5/2}]$ and $[{2}_{1}^{+}\ensuremath{\bigotimes}{g}_{7/2}]$ multiplets provides the first quantitative evidence for Pauli blocking in a spherical odd-mass nucleus. The unpaired particle is used to probe the microscopic structure of the first ${2}^{+}$ state of the adjacent core nuclei $^{140}\mathrm{Ce}$ and $^{142}\mathrm{Nd}$.
