Abstract	Complementary studies of $^{191}$Pb have been made in the $\beta$- decay of $^{191}$Bi at LISOL (CRC) and in the $\alpha$- decay of $^{195}$Po at ISOLDE (CERN). Fine structures in the $\alpha$- decay of the low-spin and high-spin isomers of $^{195}$Po have been fully resolved. Identification of the parent state is made possible via isomer selection based on narrow-band laser frequency scanning. The $\alpha$-particle and $\gamma$-ray energies have been determined with greater precision. New $\alpha$-particle and $\gamma$-ray energies are identified. Branching ratios in the decay of $^{195}$Po and $^{191}$Pb have been examined.
