A new 92Ru neutron-deficient isotope

Discovery of yttrium, zirconium, niobium, technetium, and ruthenium isotopes

“…The results were confirmed later in the same year [156]. Only a week after the second paper, de Jesus and Neirinckx independently observed 92 Ru [157].…”

“…Arlt et al published the first observation of 92 Ru in 1971 in "The New Isotope 92 Ru" [155]. Silver chloride was bombarded with 660 MeV protons from the JINR synchrocyclotron.…”

“…The isotopes were produced using projectile fission of 238 U at 750 MeV/nucleon on a lead target at GSI, Germany. "Forward emitted fragments from80 Zn up to155 Ce were analyzed with the Fragment Separator (FRS) and unambiguously identified by their energy-loss and time-of-flight." This experiment yielded 413, 81, and 10 counts, of108 Nb,109 Nb, and 110 Nb, respectively.4.26.…”
