Physical Review C—Nuclear Physics, 2007•APSWith a high energy-resolution of Δ E= 21 keV in the S 34 (He 3, t) Cl 34 measurement at 0°
and at 140 MeV/nucleon, strengths of Fermi and Gamow-Teller (GT) transitions between T
z=+ 1 and T z= 0 states were studied, where T z is the z component of isospin T. The
corresponding isospin-symmetric transitions connecting T z=-1 and T z= 0 states can be
studied in the Ar 34 β+ decay. The strengths of corresponding GT transitions were compared
up to the excitation energy (E x) of 3.1 MeV. A good agreement was observed for the two …

With a high energy-resolution of keV in the () measurement at and at 140 MeV/nucleon, strengths of Fermi and Gamow-Teller (GT) transitions between and states were studied, where is the component of isospin . The corresponding isospin-symmetric transitions connecting and states can be studied in the decay. The strengths of corresponding GT transitions were compared up to the excitation energy () of 3.1 MeV. A good agreement was observed for the two strong transitions to states around MeV, while a disagreement of 40% was observed for a weaker transition to a low-lying state.
