Abstract

The first 2⁺ states in ¹³⁴Ce and ¹³⁶Nd and the second 2⁺ state in ¹³⁶Nd were populated by Coulomb excitation at relativistic energies, and γ-rays were measured using the RISING setup at GSI. For ¹³⁴Ce an indication of the excitation to the second 2⁺ state was observed. This experiment performed for the first time Coulomb excitation to second 2⁺ states with rare isotope beams at relativistic energies. For ¹³⁶Nd the B (E 2 ; 2₁ ⁺ → 0⁺), B (E 2 ; 2₂ ⁺ → 0⁺), and B (E 2 ; 2₂ ⁺ → 2₁ ⁺) values relative to the previously known B (E 2 ; 2₁ ⁺ → 0⁺) value for ¹³⁴Ce are determined as 81(10), 11(3) and 180(92) W.u., respectively. The results are discussed in the framework of geometrical models that indicate pronounced γ-softness in these nuclei.
