Proton capture resonance spins by multidimensional scaling:fpnuclei

The method of nonmetric multidimensional scaling has been used to attribute spins to a large number of proton capture resonances in five fp-shell nuclei, $^{47}\mathrm{V}$, $^{51}\mathrm{Mn}$, $^{53}\mathrm{Mn}$, $^{55}\mathrm{Co}$, and $^{61}\mathrm{Cu}$, using as input information only the gamma decay branching ratios. The calibration of the method relies on the measured spins of a number of the resonances. In more than half the cases, a unique spin is found. The results of the analysis allow a reappraisal of analog states in the five nuclei.
