The energy levels of 120 Sn were studied by high resolution measurements of γ-rays from the (n, n′γ) reaction in the energy range 2.0–3.1 MeV. Fifteen levels at 1171, 1874, 2096, 2159, 2193, 2287, 2355, 2400, 2420, 2465, 2587, 2643, 2699, 2727 and 2835 keV were determined, and the spin-parity values were examined for twelve of them. The spin assignments were made by comparing the observed γ-ray angular distributions and level excitation functions with those calculated on the basis of statistical theory. |
