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

)
=

83645.5
(

)
keV and $${\textrm{ME}(^{95}\textrm{Y}) = -81226.4(10)}$$
ME
(

)
=

81226.4
(

)
keV, deviate by 6.5(52) keV and $$-18(7)$$
-
18
(

)
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.
