Abstract: | The masses of over sixty short-lived Rb, Sr, Cs, Ba, Fr and Ra isotopes have been measured at the on-line mass separator ISOLDE at CERN/Geneva by determination of their cyclotron frequency in the tandem Penning trap system ISOLTRAP. Resolving powers exceedingm/ m(FWHM)=106 and accuracies of typically m/m=10–7 could be achieved. ISOLTRAP can also act as an isomer separator, as proven for the cases of84Rb and78Rb. |
