Fast-timing lifetime measurement of ¹⁵²Gd

NUCLEAR REACTIONS ¹⁴⁹Sm(α, n), E=17.5 MeV; measured Eγ, γγ-coin, level half-lives by γγ(t) fast timing technique (FEST) at NIPNE-Bucharest Tandem accelerator facility. ¹⁵²Gd; deduced levels, B(E2), E0 transition strength for excited 0+ state to the ground state, indication of a quantum phase transition (QPT). Comparison with previous experimental results. Systematics of B(E2) products and E0 strength for ^{146,148,150,152,154,156,158}Gd, ^{148,150,152,154}Sm.

RADIOACTIVITY ¹⁵²Eu(β^-), (EC); measured Eγ, level half-lives by γγ(t) fast-timing technique. ¹⁵²Gd, ¹⁵²Sm; deduced levels, B(E2).
