Abstract
The use of an on-line mass spectrometer to make direct mass measurements of short-lived isotopes far from the stability line has been improved to yield more accurate mass measurements for , new mass measurements for , , and to remove a discrepancy between existing mass measurements of . The mass excesses (keV) measured are: , 40940±80; , -6901±25; , -5620±60; , -1140±80; , 2650±100; , 8370±200; , 10600±800; , 16400±1100. The value indicates that it is bound by only 170±80 keV. The masses of and imply that these nuclei are more tightly bound than expected from theoretical predictions.
