Excited states in mirror nuclei 31S and 31P were populated in the 1n and 1p exit channels,
respectively, of the reaction 20Ne + 12C. The beam of 20Ne, with an energy of 33 MeV, was delivered for the
first time by the Piave-Alpi accelerator of the Laboratori Nazionali di Legnaro. Angular correlations of
coincident pairs and Doppler-shift attenuation lifetime measurements in 31S and 31P were performed using the
multidetector array GASP in conjunction with the EUCLIDES charged particle detector. A comparison of the
determined B(E1) strengths of the analog mirror 7/2− → 5/2+ transitions indicates the presence of a violation
of isospin symmetry.
