    "abstract": "We present Gamow-Teller strength distributions from shell model Monte Carlo\nstudies of fp-shell nuclei that may play an important role in the pre-collapse\nevolution of supernovae. We then use these strength distributions to calculate\nthe electron-capture cross sections and rates in the zero-momentum transfer\nlimit. We also discuss the thermal behavior of the cross sections. We find\nlarge differences in these cross sections and rates when compared to the naive\nsingle-particle estimates. These differences need to be taken into account for\nimproved modeling of the early stages of type II supernova evolution.",
