ABSTRACT
Solar or supernova neutrinos incident on an iodine-bearing liquid will produce the noble gas 127Xe (τ1/2 = 36.4 d), which can be recovered and counted as in the present 37Cl experiment. The rate of neutrino reactions per unit volume of detector could be more than an order of magnitude greater than in perchloroethylene. I discuss the new physics that might be learned from such an experiment.
