Experimental data on the /b B/(E2)s between levels with low spin (/b I/<or=11/2) in even-even and odd-/b A/ nuclei are examined, in the framework of algebraic nuclear models, searching for evidences of a finite number of bosons. Positive indications are obtained when comparing even-even and odd-/b A/ nuclei associated in a supermultiplet by a supersymmetry.
