Double blocking in doubly odd deformed nuclei: The case of 178Re

The nature of the first band crossing in the heavy rare-earth region is an important open spectroscopic problem. Both h 9/2 protons and i 13/2 neutrons are likely to be responsible for this phenomenon. The results of a double blocking experiment in 178Re strongly suggest that in fact a pair of h 9/2 protons and of i 13/2 neutrons are simultaneously playing a role
