The 93Ag isotope is expected to be unbound towards proton emission.
1994He28: a few events (≈4 per 1014 106Cd ions) were tentatively assigned to 93Ag in Ni(106Cd,X),E=60 MeV/nucleon using projectile fragment separator at NSCL-MSU facility; however, the attribution of these events to contamination from neighboring peaks in the Z and Q spectra could not be ruled out. The flight time through the separator, was on the order of 150 ns.
1995Ry03: few events were very tentatively assigned to 93Ag in Ni(112Sn,X),E=58,62 MeV/nucleon using LISE3 separator at GANIL. Time of flight was ≈1.5 μs.
2008KrZW: 93Ag from fragmentation of 1 GeV/nucleon 124Xe beam; fragment recoil separator at GSI; ΔE, tof and magnetic rigidity measurements used for fragment identification; fragments stopped in Si implantation detector and β absorber (SIMBA).
2016Ce02: 93Ag nuclide produced and identified at RIBF-RIKEN facility in 9Be(124Xe,X) reaction at E=345 MeV/nucleon with an average beam intensity of 30 pnA. Identification of 93Ag was made by determining atomic Z and mass-to-charge ratio α/Q, where Q=charge state of the ions. The selectivity of ions was based on magnetic rigidity, time-of-flight and energy loss using BigRIPS separator and zero degree spectrometer ZDS. The separated nuclei were implanted in a wide range silicon-strip stopper array for ion and β particle detection WAS3ABi, consisting of three highly-segmented 1 mm thick double-sided silicon detectors, a stack of ten segmented 1 mm thick single-sided silicon strip detectors. The γ rays were detected by EURICA array of 84 HPGe detectors surrounding the WAS3ABi system. In addition an array of 18 LaBr3(Ce) detectors was used for γ detection in fast-timing measurements. α total of 31 events were assigned to 93Ag. 2015MoZZ is a conference report from the same group as 2016Ce02
