INVESTIGATION OF ΔI = 1 LEVEL STAGGERING IN DOUBLY ODD TANTALUM NUCLEI

The anomalous energy staggering present in odd-odd normal deformed ^168-174Ta nuclei are investigated and parameterized by proposing two staggering functions S(I) and e(I) depending on the dipole transitions ܧγ1 (I →I−1) and quadrupole transition ܧγ2 (I →I−2) linking the levels. These staggering functions differing from the conventional staggering function depending on the concept of gamma transition energy over spin 𝐸𝐺𝑂𝑆 (I)=𝐸γ1/2I. The signature α=0 has been found laying lower than that the = 1 , and an anomalous odd-even signature splitting of the πℎ11/2⊗ 𝑣i13/2 bands is happened.
