BS>A new level scheme is proposed for Sn . The levels proposed are the 1.17, 2/sup +/; 2.20, 4/sup 4/; 2.29, 5/sup -/; and 2.49 Mev, 7/sup -/ levels, which is concluded from the revision of the order of the cascade transition from the upper levels; the revised order of radiations are 0.20, E2; 0.09, El; 1.03, E2; and 1.17 Mev, E2. The transition probabilities of the 0.20- and 0.09-Mev gamma rays are also revised as 1.6 x 10/sup -3/ and 3.5 x 10/sup -5/ in units of a single-proton transition. A weak cross-over 1.12-Mev E3 transition is observed whose probability is also reduced by the factor of 1.5 x 10/sup -1/. All the results of the present experiment together with other data are discussed in terms of the theory of Kisslinger and Sorensen. It is shown particularly that the striking reduction of the 0.26-Mev E2 transition in Sn/sup 118/ as well as that of the 0.20-Mev E2 transition in Sn/sup 120/ is explained as a consequence of the pairing correlation.
