  • We present a simplified analysis using equations for the charge flow, which include ν_e capture, for the production of r-process nuclei in the context of the recent supernova hot bubble model. The role of ν_e capture in speeding up the charge flow, particularly at the closed neutron shells, is studied together with the β flow at freezeout and the effect of neutrino-induced neutron emission on the abundance pattern after freezeout. It is shown that a semiquantitative agreement with the gross… CONTINUE READING
