High-precision masses of neutron-deficient rubidium isotopes using a Penning trap mass spectrometer
/ Kellerbauer, A G (CERN) ; Audi, G ; Beck, D ; Blaum, K ; Bollen, G ; Guénaut, C ; Herfurth, F ; Herlert, A ; Kluge, H J ; Lunney, D et al.
The atomic masses of the neutron-deficient radioactive rubidium isotopes $^{74-77,79,80,83}$Rb have been measured with the Penning trap mass spectrometer ISOLTRAP. Using the time-of-flight cyclotron resonance technique, relative mass uncertainties ranging from $1.6 \times 10^{-8}$ to $5.6 \times 10^{-8}$ were achieved. [...]

High-precision mass measurements of more than thirty neutron-rich nuclides around the Z=28 closed proton shell were performed with the triple-trap mass spectrometer ISOLTRAP at ISOLDE/CERN to address the question of a possible neutron shell closure at N=40. The results, for 57,60,64-69Ni (Z=28), 65-74,76Cu (Z=29), and 63-65,68-78Ga (Z=31), have a relative uncertainty of the order of 10^8. [...]
