Query: Transient Joule- and (ac) Josephson-like photon emission in one- and
  two- nucleon tunneling processes between superfluid nuclei: blackbody and
  coherent spectral functions   Effective charged neutrons involved in one- and two- nucleon tunneling
processes in heavy ion collisions between superfluid nuclei are expected to
emit photons. Although the centroid, width and integrated energy area
characterizing the associated gamma-strength functions are rather similar, the
corresponding line shapes reflect the thermal equilibrated-like character of
the quasiparticle transfer (1n-channel, blackbody spectral functional
dependence), and the quantal coherent character of the Cooper pair transfer
(2n-channel, Gaussian functional dependence) respectively. The predicted
angular distributions, polarizations and analyzing power provide further
insight into the profoundly different physics to be found at the basis of what
can be considered a transient Joule-like and a (ac) Josephson-like nuclear
processes
