“…spectra, the previously noted uncertainty in mixing of shell-model states at the relevant excitation suggests that the meaningful quantity is a range of energy ( Fig. 2) [10], the major part of the lowest mixed-symmetry O(6) 2+ state appears to reside in the second level at 3.075 MeV, with the 1+ expected in the vicinity of 3.4 MeV. However, the emphasis of this work is on the identification of a particular mode, in this case that described by the O(6) dynamical symmetry, and on the location of the associated strength where this is not readily done by experiment because M1 transitions to the lowest states vanish or are small, such as for the higher spin states or those dominated by the higher O(5) multiplets (Fig.…”

Gamow-Teller strength distributions for nuclei in presupernova stellar cores

“…For 54 Fe we note that ref. [27] gives only the Isobaric Analog States corresponding to a few excited levels of 54 Mn. The difference of the IAS energies and the corresponding levels in 54 Mn are in the range of 8.59 to 8.79 MeV.…”
