Abstract
Neutron-deficient isotopes with Z = 21 to 26 have been produced as projectile-like fragments of an intense {sup 58}Ni GANIL beam of 69 MeV/nucleon. The nuclei selected by the upgraded LISE3 spectrometer were identified and implanted in a silicon detector telescope. The {sup 43}Cr, {sup 47}Fe and {sup 46}Fe isotopes were identified for the first time whereas {sup 45}Fe, {sup 45}Mn, {sup 44}Mn and {sup 42}V were not observed, indicating probable instability of these nuclei against particle emission. Measurements of the half-lives of {sup 43}Cr and {sup 46} Mn have been performed and the analysis of their measured beta-delayed proton spectra has given, through the Isobaric Multiplet Mass Equation, an empirical estimation of their masses. Half-lives of {sup 44}Cr, {sup 43}V, {sup 47}Fe and {sup 46}Fe have also been measured. A discussion of various mass predictions for nuclei at the proton drip-line is given.
