    Abstract

    The mass-measurement programme at GANIL aims to measure the masses of heavy nuclei close to the N = Z line which is the ideal region to study neutron-proton pairing. An original direct time-of-flight mass-measurement method was developed at GANIL which uses the CSS2 cyclotron as a high-resolution spectrometer. The masses of ions of A = 68, 76, 80 and 100 have been measured with a precision of a few 10-6. Mass measurements will be performed with the new CIME cyclotron of SPIRAL using a similar method based on the measurement of the phase of the accelerated ions for different radio-frequencies. A recently approved experiment will help develop this new technique and aims to measure the mass of 31Ar radioactive nuclei with a precision of 10-6.
