Abstract

A search for new proton-rich isotopes using projectile fragmentation of a 345-MeV/nucleon Xe124 beam has been performed with the BigRIPS in-flight separator at the RIKEN Nishina Center RI Beam Factory. Projectile fragments were identified by measuring the time of flight, magnetic rigidity, and energy loss in the BigRIPS separator. Projectile fragments then were transported downstream of the BigRIPS separator and re-identified by measuring the time of flight and total kinetic energy. Through such particle re-identification, we have discovered four new isotopes Mo81,82 and Ru85,86 located near the proton drip line. The Y76 and Zr78 isotopes near the proton drip line also were identified, supporting the previous report on their discovery. Furthermore, we have obtained the first clear evidence for the particle instability of Sb103. Based on the systematics of measured production yields, the upper limit values were evaluated for the half-lives of the particle-unbound isotopes Nb81,Tc85, and Sb103.
