Abstract: Gamow-Teller (GT) transitions can be studied in both β-decay and charge exchange(CE) reactions. If isospin is a good quantum number, then the T<subscript>z</subscript> = -1→0 and T<subscript>z</subscript> = +1→0 GT mirror transitions, are identical. Therefore, a comparison of the results from studies of β decay and CE should shed light on this assumption. Accordingly we have studied the β decay of the T<subscript>z = -1</subscript> fp-shell nuclei, <superscript>54</superscript>Ni, <superscript>50</superscript>Fe, <superscript>46</superscript>Cr, and <superscript>42</superscript>Ti, produced in fragmentation and we have compared our results with the spectra from (<superscript>3</superscript>He, t) measurements on the mirror T<subscript>z</subscript> = +1 target nuclei studied in high resolution at RCNP, Osaka. The β-decay experiments were performed as part of the STOPPED beam RISING campaign at GSI. [ABSTRACT FROM AUTHOR]
