N2 - The atomic masses of the alkali-metal isotopes Li6,Na23,K39,41,Rb85,87, and Cs133 have been obtained from measurements of cyclotron frequency ratios of pairs of ions simultaneously trapped in a Penning trap. The results, with one standard deviation uncertainty, are: M(Li6)=6.015 122 887 4(16)u,M(Na23)=22. 989769 282 8(26)u,M(K39)=38.963 706 485 6(52)u,M(K41)=40.961 825 257 4(48)u,M(Rb85)=84.911 789739(9)u,M(Rb87)=86.909 180 535(10)u, and M(Cs133)=132.905 451 963(13)u. Our mass of Li6 yields an improved neutron separation energy for Li7 of 7251.1014(45) keV.
