Abstract Neutron-deficient isotopes with Z=21 to 26 have been produced as projectile-like fragments of an intense58Ni GANIL beam of 69 MeV/nucleon. The nuclei selected by the upgraded LISE3 spectrometer were identified and implanted in a silicon detector telescope. The43Cr,47Fe and46Fe isotopes were identified for the first time whereas45Fe,45Mn,44Mn and42V were not observed, indicating probable instability of these nuclei against particle emission. Measurements of the half-lives of43Cr and46Mn 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 of44Cr,43V,47Fe and46Fe have also been measured. A discussion of various mass predictions for nuclei at the proton drip-line is given.
