General Comments:

2011FuZZ: Be(48Ca,X) with E(48Ca)=345 MeV/nucleon. Isotopes separated with the BigRIPS in-flight separator and identified through Bρ, time-of-flight, and energy loss measurements. Measured production cross section for 41Si as σ≈10-4 mb (value extracted from Figure 1 by evaluators).

2007Ta15: 9Be(48Ca,X) and natW(48Ca,X) reactions with E(48Ca)=142 MeV/nucleon. Fragments separated with the A1900 fragment separator and identified using ΔE, Bρ, total energy and time-of-flight measurements. Measured production cross section for 41Si as σ=1.3×10-5 mb +6-8 for the W target.

2004Gr20: 9Be(48Ca,X) reaction with E(48Ca)=60 MeV/nucleon. Fragments separated with the LISE3 spectrometer and identified on a event-by-event basis using ΔE and time-of-flight measurements. Measured implant-β(t); deduced T1/2. Subset of results given in 2004Gr28, 2003Gr22.

1999YoZW: 9Be(48Ca,X) and 181Ta(48Ca,X) reactions with E(48Ca)=70 MeV/nucleon. Fragments separated with the RIPS spectrometer and identified by measuring time-of-flight and energy deposition into two Si detectors. Measured implant-β(t) using a Si detector and β-neutron coincidences using 46 3He proportional counters; deduced preliminary T1/2 values and tentative β-delayed neutron emission probabilities.

1989Gu03: 181Ta(48Ca,X) reaction with E(48Ca)=55 MeV/nucleon. Fragments separated by the achromatic LISE spectrometer and identified using ΔE, total energy, Bρ, and time-of-flight measurements. Established particle stability of 41Si.

Q-value: ΔS(p)=620; ΔQ(α)=620 (2012Wa38)

Q-value: S(2n)=6.3×103 4; S(2p)=44730 syst 630; Q(β-n)=1.21×104 4 (2012Wa38)
