摘要: A spectroscopic study of Sb-108 has been carried out as a part larger experiment where in total twenty-nine different residual nuclei were identified. This gives the first information on excited levels this nucleus. low-lying two-quasi-particle multiplet together with some higher lying are discussed within framework nuclear shell model. rotational, strongly coupled, band is identified as, most likely, being built deformed pig9/2(-1) nuh11/2 configuration accordance routhian surface calculations. Tentative spins and parities presented well B(M1)/B(E2) ratios for transitions coupled band.
