High spin states in the Kπ = 1 2- band of 19F
Nuclear Physics, Section A 225:2 (1974) 253-266
Abstract:
Resonances in the 15N(α, γ)19F reaction at Eα = 5413 ± 5 keV and 6258 ± 5 keV corresponding to levels in 19F at Ex = 8288 ± 2 keV and 8957 ± 2 keV have been studied. Angular distribution and ωγ measurements indicate that the level at 8288 keV has Jπ = 13 2-( 9 2-),while that at 8957 keV has Jπ = 11 2+. The values of ωγ are 0.53 ± 0.08 eV and 0.9 ± 0.17 eV respectively. The 8288 keV level decays by a 22.4 ± 3.3 W.u. E2 transition to the 9 2- state at 4032 keV and is suggested to be the 13 2- member of the Kπ = 1 2- band. © 1974.A more accurate mass for He8

Abstract:
The Mg26(, He8)Mg22 reaction was reinvestigated at a bombarding energy of 110.6 MeV with a magnetic spectrometer-multiwire proportional counter detection system, leading to an improved value for the mass excess of He8 of 31.570.03 MeV.

Abstract:
The reactions (α,Be9), (α, Be7), and (Li6, B8) on Ca48 at E(α)=78 MeV and E(Li6)=80 MeV were used to determine the mass excesses of Ar43 (-31.98 ± 0.07 MeV), Ar45(-29.727 ± 0.06 MeV), and Ar46 (-29.732 ± 0.07 MeV) by counter telescope techniques. Excited states in Ar43 at 1.74 ± 0.05, 2.55 ± 0.05, 3.56 ± 0.07, and 4.74 ± 0.10 MeV and in Ar45 at 1.66 ± 0.05, 2.42 ± 0.05, and 3.25 ± 0.07 MeV were also observed. Comparisons are made with mass predictions calculated from simple mass relations based on the shell model and with those obtained from the Garvey and Kelson approach.
