General Comments:

2011StZW (also 2008KrZW): production and identification of 95Cd in 9Be(124Xe,X) at E=1 GeV/nucleon. Measured yield and half-life of the decay of 95Cd using FRS separator and RISING detector array for γ rays at GSI facility. Fig. 3.5 of α/Q versus Z particle identification plot, 42 counts were assigned to 95Cd (in Fig. 3 of 2008KrZW, about ten events seem assigned to 95Cd).

2016Ce02: 95Cd 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 95Cd 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.

2017Da07: 95Cd produced in fragmentation of 345 MeV/nucleon 124Xe beam on a 740 mg/cm2 9Be target at RIBF-RIKEN facility. Fragments were separated using the BigRIPS separator, followed by implantation into the active stopper SIMBA consisting of three double-sided silicon strip detectors (DSSSDs), and surrounded by the EURICA array consisting of 84 HPGe detectors. Measured Eγ, Iγ, E(p), I(p), βγ-coin, β+p-coin, β+γp-coin, and half-life of the decay of 95Cd.

2018Pa20: 95Cd 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 95Cd 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. No beta-delayed γ rays were observed in the decay of 95Cd. 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. 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

2018Pa20, 2017Da07 and 2016Ce02 are from experiments at the same laboratory (RIBF-RIKEN facility), with some of the same authors on these three papers.

Q-value: Estimated uncertainties (2017Wa10): 640 for S(n), 570 for S(p) and Q(α)

Q-value: S(2p)=2210 500, Q(εp)=12180 400, Q(ε)=12970 500 (syst, 2017Wa10); 10.2 MeV 17 (2018Pa20, from implants-β+ correlated energy curve, assuming that the observed endpoint energy corresponds to g.s. to g.s. β+ transition). S(2n)=32120 (theory, 2019Mo01)
