Abstract

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