Effectively charged neutrons involved in one- and two-nucleon tunneling processes in heavy-ion collisions between superfluid nuclei are expected to emit photons. The predicted line shapes reflect the different physics characteristics.
Effectively 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 (1 n channel, blackbody spectral functional dependence) and the quantal coherent character of the Cooper pair transfer (2n channel, and Gaussian functional dependence), respectively. The predicted angular distributions, polarizations, and analyzing powers provide further insight into the profoundly different physics to be found at the basis of what can be considered transient Joule-like and (ac) Josephson-like nuclear processes.
