Reinvestigation of ${}^{91}$Sr and ${}^{95}$Y atomic masses using the JYFLTRAP Penning trap

We report on the precise mass measurements of the ${}^{91}$Sr and ${}^{95}$Y isotopes performed using the JYFLTRAP double Penning trap mass spectrometer. The mass-excess values from this work, ME(${}^{91}$Sr) = -83645.5(13) keV and ME(${}^{95}$Y) = -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 ${}^{91}$Sr the new result disagrees with the ISOLTRAP value, while for ${}^{95}$Y, it agrees with the older JYFLTRAP value.
