  • Comparing experimental and calculated electron-capture rates of pf-shell nuclei in explosive stellar environments 
    Cole, A.L.; Anderson, T.S.; Austin, S.M.; Brown, B.A.; Dombos, A.C.; Fawwaz, O.; Gupta, S.; Hitt, G.W.; Schooley, A.K.; Valdez, L.; Zegers, R.G.T. Z (2016-12-01)
    In explosive stellar environments electron-capture rates on pf-shell nuclei are needed to model core-collapse and thermonuclear supernovae. Electron-capture (EC) rates can be determined from Gamow-Teller (GT) transitions ...
  • Gamow-Teller strengths and electron-capture rates for pf-shell nuclei of relevance for late stellar evolution 
    Cole, A.L.; Anderson, T.S.; Zegers, R.G.T.; Austin, S.M.; Brown, B.A.; Valdez, L.; Gupta, S.; Hitt, G.W.; Fawwaz, O. (2016-12-01)
    Background: Electron-capture reaction rates on medium-heavy nuclei are an important ingredient for modeling the late evolution of stars that become core-collapse or thermonuclear supernovae. The estimation of these rates ...
  • The Impact of Neutron Transfer Reactions on the heating and cooling of Accreted Neutron Star Crusts 
    Schatz, H.; Meisel, Z.; Brown, E.F.; Gupta, S.S.; Hitt, G.W.; Hix, W.R.; Jain, R.; Lau, R.; Moller, P.; Ong, W.-J.; Shternin, P.S.; Xu, Y.; Wiescher, M. (2022-06-22)
    Nuclear reactions heat and cool the crust of accreting neutron stars and need to be understood to interpret observations of X-ray bursts and long-term cooling in transiently accreting systems. It was recently suggested ...
  • Impact of Pycnonuclear Fusion Uncertainties on the Cooling of Accreting Neutron Star Crusts 
    Jain, R.; Brown, E.F.; Schatz, H.; Afanasjev, A.V.; Beard, M.; Gasques, L.R.; Gupta, S.S.; Hitt, G.W.; Hix, W.R.; Lau, R. (2024-06-09)
    Abstract: The observation of X-rays during quiescence from transiently accreting neutron stars provides unique clues about the nature of dense matter. This, however, requires extensive modeling of the crusts and matching ...
  • β+ Gamow-teller transition strengths from Ti 46 and stellar electron-capture rates 
    Noji, S.; Zegers, R.G.T.; Austin, S.M.; Baugher, T.; Bazin, D.; Brown, A.B.; Campbell, C.M.; Cole, A.L.; Doster, H.J.; Gade, A.; Guess, C.J.; Gupta, S.; Hitt, G.W.; Langer, G.; Lipschutz, S.; Lunderberg, E.; Meharchand, R.; Meisel, Z.; Perdikakis, G.; Pereira, J.; Recchia, F.; Schatz, H.; Scott, M.; Stroberg, S.R.; Sullivan, C.; Valdez, L.; Walz, C.; Weisshaar, D.; William, S.J.; Wimmer, K. (2016-11-22)
    The Gamow-Teller strength in the β+ direction to Sc46 was extracted via the Ti46(t,He3+γ) reaction at 115MeV/u. The γ-ray coincidences served to precisely measure the very weak Gamow-Teller transition to a final state at ...
