The photon spectrum in macrocoherent atomic de-excitation via radiativeemission of neutrino pairs (RENP) has been proposed as a sensitive probe of theneutrino mass spectrum, capable of competing with conventional neutrinoexperiments. In this paper we revisit this intriguing technique in order toquantify the requirements for statistical determination of some of theproperties of the neutrino spectrum, in particular the neutrino mass scale andthe mass ordering. Our results are sobering. We find that, even under idealconditions, the determination of neutrino parameters needs experimental livetimes of the order of days to years for several laser frequencies, assuming atarget of volume of order 100 cm3 containing about 10^21 atoms per cubiccentimeter in a totally coherent state with maximum value of the electric fieldin the target. Such conditions seem to be, as of today, way beyond the reach ofour current technology.
