AB  - Lifetime measurements of low-lying excited states in the semimagic (N = 50) nucleus <sup>95</sup>Rh have been performed by means of the fast-timing technique. The experiment was carried out using  γ-ray detector arrays consisting of LaBr<sub>3</sub>(Ce) scintillators and germanium detectors integrated into the DESPEC experimental setup commissioned for the Facility for Antiproton and Ion Research ( fair) Phase-0, Darmstadt, Germany. The excited states in <sup>95</sup>Rh were populated primarily via the β decays of <sup>95</sup>Pd nuclei, produced in the projectile fragmentation of a 850 MeV/nucleon <sup>124</sup>Xe beam impinging on a 4 g/cm<sup>2</sup> <sup>9</sup>Be target. The deduced electromagnetic E2 transition strengths for the γ-ray cascade within the multiplet structure depopulating from the isomeric I<sup>π</sup> = 21/2<sup>+</sup> state are found to exhibit strong deviations from predictions of standard shell model calculations which featureapproximately conserved seniority symmetry. In particular, the observation of a strongly suppressed E2 strength for the 13/2<sup>+</sup> → 9/2<sup>+</sup> ground state transition cannot be explained by calculations employing standard interactions.This remarkable result may require revision of the nucleon-nucleon interactions employed in state-of-the-art theoretical model calculations, and might also point to the need for including three-body forces in the Hamiltonian.
