Abstract. Structural investigation of ¹⁰¹Pd by E-GOS (E-Gamma Over Spin) method and systematic of νh_11/2 bands in neighboring even-Z and odd-N nuclei has been studied by plotting the ratio of Gamma Ray Energy divided by spin against that spin. Afterwards, we arranged the plots in order of increasing nucleon number. The concept of the E-Gamma Over Spin or E-GOS prescription has been applied to a number of even-even nuclei in vicinity of the A = 110 mass region with the conclusion that many of these nuclei exhibit a decay sequence consistent with quasi-vibrational bands. Plotting the E-GOS curves in this manner shows a clear transition from vibrational to rotational motion like character in some bands.The concept of the E-Gamma Over Spin or E-GOS prescription has been applied to a number of even-even nuclei around the ∼ 110 mass region. The level scheme of the ¹⁰¹Pd has been studied within the framework of E-GOS approach. The results are interpreted using the E-GOS prescription, modified for use with odd-A nuclei. Both of these analyses highlight the role of the low-Ω intruder orbital in stabilizing the quadruple deformation in this region. The νh_11/2 bands in some neighboring even-Z and odd-N nuclei exhibit vibrational to rotational character.
