Data analysis techniques for extracting Gamow–Teller strengths from 0° (p,n) data

Techniques are described to obtain absolute normalizations for Gamow–Teller strength functions from (p,n) spectra. A method using data taken at two different proton energies and a method using polarization transfer data are discussed. Both methods require determining the number of counts due to the Fermi transition which is usually not completely resolved. We discuss methods for normalizing to unresolved Fermi peaks and handling peak shapes encountered in real time-of-flight spectra.
