Evolution of quadrupole collectivity in N=80 isotones toward the Z=64 subshell gap: The B(E2; 2⁺₁ → 0⁺₁) value of ¹⁴²Sm

NUCLEAR REACTIONS ⁴⁸Ti, ⁹⁴Mo(¹⁴²Sm, ¹⁴²Sm'), E=405 MeV, [secondary ¹⁴²Sm beam from Ta(p, X), E=1.4 GeV from PS booster at CERN and using RILIS and GPS setup at ISOLDE-CERN]; measured Eγ, Iγ, (particle)γ-coin, γ-particle yields as function of angle using MINIBALL HPGe-detector array at REX-ISOLDE-CERN facility. Coulomb excitation technique. ¹⁴²Sm; deduced matrix elements and B(E2) for the first 2+ state in ¹⁴²Sm. Systematics of B(E2) values for first 2+ state in ¹³⁰Sn, ¹³²Te, ¹³⁴Xe, ¹³⁶Ba, ¹³⁸Ce, ¹⁴⁰Nd, ¹⁴²Sm. Comparison with shell-model calculations.

RADIOACTIVITY ¹⁴²Pm, ^142,142mEu, ¹⁴²Sm(EC), (β⁺); measured Iγ; deduced ^142mEu/¹⁴²Eu isomeric ratio, and M(¹⁴²Eu)/M(¹⁴²Sm).
