| 0 | (9/2+) | 36 ms 6 % β+ = 100 % β+p = 1.7 +17-8 | ε decay considered negligible by 2018Pa20. E(level): ε decay considered negligible by 2018Pa20. |
| 0.61E3 | (1/2-) | 0.12 ms 11 % p = ? | In beta-delayed gamma-ray spectrum, a peak at 421 keV was observed with 9 4 counts, with the decay curve giving a half-life of 1.7 s 7, consistent with the tentative assignment of 421γ as a (1+) to (2+) transition in 96Ag from the decay of 96Cd, as reported by 2011Na34. α strong 421-keV γ was also seen by 2017Da07, and assigned as a low-lying transition in 96Ag. 2018Pa20 proposed that the isomer decayed by direct proton decay to 96Cd.

2008KrZW, 2011StZV: production and identification of 97In in 9Be(124Xe,X),E=1 GeV/nucleon. Measured yield using Fragment separator, SIMBA implantation detector system and RISING detector array for γ rays. Measured production σ from observed 25 counts assigned to 97In
2018Pa20: 97In nuclide produced at RIBF-RIKEN facility in 9Be(124Xe,X) reaction at E=345 MeV/nucleon with target thickness of 740 mg/cm2. Identification of 97In 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 first on magnetic rigidity (Bρ), and energy loss (ΔE) using BigRIPS separator and, in the second stage by Bρ-tof-ΔE measurement in the later stages of BigRIPS separator and ZeroDegree spectrometer (ZDS) using position-sensitive parallel-plate avalanche counters, plastic scintillators, and a gas-filled ionization chamber. The flight time through the separation and identification systems ranged from 600 to 630 ns depending on α and Z. The separated nuclei were implanted in a wide range segmented silicon-strip stopper array for ion and β particle detection system WAS3ABi, consisting of three highly-segmented 1 mm thick double-sided silicon strip detectors (DSSSDs). Q(β) value was measured using ten single-sided segmented strip detectors (SSSSDs) placed farther downstream. Measured (implant)β correlated decay curve, with a time correlation window of 5 seconds before and after ion implantation. The EURICA array was used for gamma-ray detection in coincidence with β particles and implants. Events for proton emission were separated from the positron events by requiring a minimum of 1500 keV energy deposited in a single pixel of a DSSSD. Production of 97In also shown in α/Q versus Z plot in Fig. 1 of 2019Pa16, where a large number of events are assigned to this isotope.
The β-decay correlation fraction was determined as the ratio of the integral of the parent β-decay fit components and the number of implanted ions which did not decay by βp events
