DESCRIPTION:Speakers: Karlheinz Langanke (GSI Darmstadt)\nNeutrinos play a
 n important role for the supernova dynamics and the \nassociated nucleosyn
 thesis. During collapse\, electron neutrinos\, produced \nby electron capt
 ure on nuclei\, dominate\, while all neutrino families are \nbeing produce
 d during the cooling phase of the protoneutron star.\n\nNeutrinos are cruc
 ial for the explosive nucleosynthesis. At first\, by \ninteraction with fr
 ee nucleons they determine the proton-to-neutron ratio \nof the ejected ma
 tter which is crucial for the subsequent \nnucleosynthesis. Modern superno
 va simulations indicate that the ejected \nmatter is not sufficiently neut
 ron rich to support an r-process which also \nproduces the solar abundance
 s in the third r-process peak.\n\nNeutrino-induced spallation reactions on
  abundant nuclei in the outer\nstellar shells are responsible for the prod
 uction of selected nuclides\n(neutrino nucleosynthesis). Recently the firs
 t study of neutrino \nnucleosynthesis has been presented which considers t
 he time-dependence\nof the neutrino emission including the neutrino burst\
 , the accretion phase \nand the cooling phase as well as changes in the sp
 ectral forms of the \nneutrinos.\n\nhttps://indico.tlabs.ac.za/event/85/co
