Four new superdeformed bands have been observed in {sup 195}Pb, the first time superdeformation has been observed in an odd-{ital A} Pb nucleus. Two of the bands have a dynamic moment of inertia that is nearly constant as a function of {h_bar}{omega}. This is the first time that bands with such behavior have been observed in an odd-{ital A} nucleus in the {ital A}{approx}190 region and it is interpreted as the result of the blocking of the alignment of neutron pairs.
