Abstract
Abstract: After an outline of the physics motivations, that illustrate why we think it is important to measure masses in the region N≈Z, we report on on experiments performed at Ganil. An experiment aimed at measuring the masses of proton-rich nuclei in the mass region A ≈ 60–80 has been performed, using a direct time-of-flight technique in conjunction with SISSI and the SPEG spectrometer at GANIL. The nuclei were produced via the fragmentation of a 78Kr beam (73 meV/nucleon). A novel technique for the purification of the secondary beams, based on the stripping of the ions and using the α and the SPEG spectrometers, was succesfully checked. It allows for good selectivity without altering the beam quality. Secondary ions of 100Ag, 100Cd, 100In and 100Sn were produced via the fusion-evaporation reaction 50Cr + 58Ni at an energy of 5.1 MeV/nucleon, and were accelerated simultaneously in the second cyclotron of GANIL (CSS2). About 10 counts were observed from the production and acceleration of 100Sn22+. The masses of 100Cd, 100In and 100Sn were measured with respect to 100Ag using the CSS2 cyclotron, with precisions of 2 × 10−6, 3 × 10−6 and 10−5 respectively.

<front><div type="abstract" xml:lang="en">Abstract: After an outline of the physics motivations, that illustrate why we think it is important to measure masses in the region N≈Z, we report on on experiments performed at Ganil. An experiment aimed at measuring the masses of proton-rich nuclei in the mass region A ≈ 60–80 has been performed, using a direct time-of-flight technique in conjunction with SISSI and the SPEG spectrometer at GANIL. The nuclei were produced via the fragmentation of a 78Kr beam (73 meV/nucleon). A novel technique for the purification of the secondary beams, based on the stripping of the ions and using the α and the SPEG spectrometers, was succesfully checked. It allows for good selectivity without altering the beam quality. Secondary ions of 100Ag, 100Cd, 100In and 100Sn were produced via the fusion-evaporation reaction 50Cr + 58Ni at an energy of 5.1 MeV/nucleon, and were accelerated simultaneously in the second cyclotron of GANIL (CSS2). About 10 counts were observed from the production and acceleration of 100Sn22+. The masses of 100Cd, 100In and 100Sn were measured with respect to 100Ag using the CSS2 cyclotron, with precisions of 2 × 10−6, 3 × 10−6 and 10−5 respectively.</div>

<abstract xml:lang="en"><p>After an outline of the physics motivations, that illustrate why we think it is important to measure masses in the region N≈Z, we report on on experiments performed at Ganil. An experiment aimed at measuring the masses of proton-rich nuclei in the mass region A ≈ 60–80 has been performed, using a direct time-of-flight technique in conjunction with SISSI and the SPEG spectrometer at GANIL. The nuclei were produced via the fragmentation of a 78Kr beam (73 meV/nucleon). A novel technique for the purification of the secondary beams, based on the stripping of the ions and using the α and the SPEG spectrometers, was succesfully checked. It allows for good selectivity without altering the beam quality. Secondary ions of 100Ag, 100Cd, 100In and 100Sn were produced via the fusion-evaporation reaction 50Cr + 58Ni at an energy of 5.1 MeV/nucleon, and were accelerated simultaneously in the second cyclotron of GANIL (CSS2). About 10 counts were observed from the production and acceleration of 100Sn22+. The masses of 100Cd, 100In and 100Sn were measured with respect to 100Ag using the CSS2 cyclotron, with precisions of 2 × 10−6, 3 × 10−6 and 10−5 respectively.</p>

<abstract lang="en">Abstract: After an outline of the physics motivations, that illustrate why we think it is important to measure masses in the region N≈Z, we report on on experiments performed at Ganil. An experiment aimed at measuring the masses of proton-rich nuclei in the mass region A ≈ 60–80 has been performed, using a direct time-of-flight technique in conjunction with SISSI and the SPEG spectrometer at GANIL. The nuclei were produced via the fragmentation of a 78Kr beam (73 meV/nucleon). A novel technique for the purification of the secondary beams, based on the stripping of the ions and using the α and the SPEG spectrometers, was succesfully checked. It allows for good selectivity without altering the beam quality. Secondary ions of 100Ag, 100Cd, 100In and 100Sn were produced via the fusion-evaporation reaction 50Cr + 58Ni at an energy of 5.1 MeV/nucleon, and were accelerated simultaneously in the second cyclotron of GANIL (CSS2). About 10 counts were observed from the production and acceleration of 100Sn22+. The masses of 100Cd, 100In and 100Sn were measured with respect to 100Ag using the CSS2 cyclotron, with precisions of 2 × 10−6, 3 × 10−6 and 10−5 respectively.</abstract>
