Low-lying collective states in ¹²⁰Cd populated by β decay of ¹²⁰Ag: Breakdown of the anharmonic vibrator model at the three-phonon level

RADIOACTIVITY ¹²⁰Ag(β^-)[from ²³⁸U(p, F), E=40 MeV]; measured Eγ, Iγ, conversion electron spectrum, (ce)γ-, γγ-coin, half-lives, branching ratio from isomer decay using CARDS array and BESCA ce spectrometer at HRIBF. ¹²⁰Cd; deduced levels, isomers, J, π, β feedings, logft, B(E2), quadrupole-octupole coupled states Systematics of decays of phonon, intruder and 3- states in ^{108,110,112,114,116,118,120,122}Cd. Comparison with multiphonon vibrational approach.
