“…Effective g-factors have been chosen to correspond to free g-factors, and two sets of global pf effective charges have been used: the so-called standard pf -shell ones, e p = 1.5 and e n = 0.5, [42], and the ones derived experimentally from heavier N ∼ Z pf nuclei, e p = 1.15 and e n = 0.80, [44]. Potential orbital dependencies of effective charges [45,46] The aim for the model calculations is to reproduce all three experimental numbers, which define an experimental basis comparable to the preceding study of the A = 51 pair [44].…”

Binding energies and other global properties of nuclei in the middle of the pf shell, such as M1, E2 and Gamow-Teller sum rules, have been obtained using a new Shell Model code (NATHAN) written in quasi-spin formalism and using a j-j-coupled basis. An extensive comparison is made with the recently available Shell Model Monte Carlo results using the effective interaction KB3. The binding energies for -nearly-all the 1f 7/2 nuclei are compared with the measured (and extrapolated) results. PACS number(s):21.10.Dr,21.60.Cs

“…This situation changed recently as the development of the shell model Monte Carlo technique (SMMC) [13][14][15] allows calculations of the GT strength distribution in the complete pf shell. In fact, using the KB3 residual interaction [16] it has been demonstrated that both the quenching of the GT strength [17] and its distribution [18] can be well reproduced. Using the SMMC method, Dean et al have recently calculated electron capture rates for several Fe peak nuclei of importance at the early stage of the presupernova collapse [19].…”

“…Due to their importance a calculation of the two rates on the basis of a shell model diagonalization approach seems to be quite useful. We have performed such a calculation for the 56 Ni ground state and the 3 lowest states in 55 Co using the KB3 interaction [16] and making use of the state-of-the-art diagonalization code ANTOINE [22].…”

We have calculated the Gamow-Teller strength distributions for the ground states and first excited states in 55 Co and 56 Ni. These calculations have been performed by shell model diagonalization in the pf shell using the KB3 interaction. The Gamow-Teller distributions are used to calculate the electron capture rates for typical presupernova conditions. Our 55 Co rate is noticeably smaller than the presently adopted rate as it is dominated by weak low-lying transitions rather than the strong Gamow-Teller (GT) resonance which is located at a higher excitation energy in the daughter than usually parametrized. Although our 56 Ni rate agrees with the presently adopted rate, we do not confirm the conventional parametrization of the GT centroid. Our results support general trends suggested on the basis of shell model Monte Carlo calculations.
