Mass measurements on neutron-deficient Sr and neutron-rich Sn isotopes with the ISOLTRAP mass spectrometer
The atomic masses of $^{76,77,80,81,86,88}$Sr and $^{124,129,130,131,132}$Sn were measured by means of the Penning trap mass spectrometer ISOLTRAP at ISOLDE/CERN. $^{76}$Sr is now the heaviest N=Z nucleus for which the mass is measured to a precision better than 35 keV. For the tin isotopes in the c...

| description | The atomic masses of $^{76,77,80,81,86,88}$Sr and $^{124,129,130,131,132}$Sn were measured by means of the Penning trap mass spectrometer ISOLTRAP at ISOLDE/CERN. $^{76}$Sr is now the heaviest N=Z nucleus for which the mass is measured to a precision better than 35 keV. For the tin isotopes in the close vicinity of the doubly magic nucleus $^{132}$Sn, mass uncertainties below 20 keV were achieved. An atomic mass evaluation was carried out taking other experimental mass values into account by performing a least-squares adjustment. Some discrepancies between older experimental values and the ones reported here emerged and were resolved. The results of the new adjustment and their impact will be presented. |
