Different deformations for the two bands built above the ({pi}{ital h}{sub 11/2}){sup 2} 10{sup +} and the ({nu}{ital h}{sub 11/2}){sup {minus}2} 10{sup +} states in {sup 140}Sm have been determined from lifetime measurements using the reaction {sup 106}Pd({sup 37}Cl,{ital p}2{ital n}){sup 140}Sm at 143 MeV. The {beta} values derived for the {ital N}=78 and {ital N}=80 core nuclei, coexisting in {sup 140}Sm, complete the systematics of nuclear deformation from {ital N}=72 to 80.
