We report on the precise mass measurements of the 91Sr and 95Y isotopes performed using the JYFLTRAP double Penning trap mass spectrometer. The mass-excess values from this work, ME(91Sr)=−83645.5(13) keV and ME(95Y)=−81226.4(10) keV, deviate by 6.5(52) keV and −18(7) keV from the Atomic Mass Evaluation 2020 (AME20). In the case of 91Sr the new result disagrees with the ISOLTRAP value, while for 95Y, it agrees with the older JYFLTRAP value.
