Neural network study of the nuclear ground-state spin distribution within a random interaction ensemble

We performed approximately 100,000 TBRE calculations in six model spaces. These included four valence nucleons in the f7/2 orbital virtual nuclear (simply expressed as (f7/2) 4 ), four valence nucleons in the h11/2 orbital virtual nuclear ((h11/2) 4 ), and two, four, and six valence neutrons in the sd shell (corresponding to 18 , 20, and 22 Ne nuclear, respectively), and six valence neutrons in the pf shell (46Ca nuclear). These six model spaces represent various levels of many-body complexity.
