Two separate experiments using the Differential Decay Curve Method have been performed to extract mean lifetimes of excited states in ¹⁰⁶Cd. The medium-spin states of interest were populated by the ⁹⁸Mo( ¹²C, 4n) ¹⁰⁶Cd reaction performed at the Wright Nuclear Structure Lab., Yale University. From this experiment, two isomeric state mean lifetimes have been deduced. The low-lying states were populated by the ⁹⁶Mo(¹³C, 3n)¹⁰⁶Cd reaction performed at the Institut für Kernphysik, Universität zu Köln. The mean lifetime of the I^π = 21 ⁺ state was deduced, tentatively, as 16.4(9) ps. This value differs from the previously accepted literature value from Coulomb excitation of 10.43(9) ps.
