Spin assignment of the first discovered superdeformed band ^152Dy（1）

Using the several criteria for the spin assignment of a rotational band based on very general argument,the spin of the lowest level observed in the yrast SD band 152Dy(1) is assigned to be I0=26(Eγ(I0+2→I0)=602.4keV),and it is demonstrated that spin assignments of I0≤25 as well as I-≥27 are in contradiction with these criteria.
