Abstract
Electromagnetic decay properties of the low-lying states in 55Fe were studied using the 55Mn(p, nγ) 55Fe reaction. The measurement of γ-ray angular distributions together with predictions based on the compound nuclear statistical model has permitted unique spin assignments to be made to the following excited states in 55Fe: 1.316 MeV ( 7 2 ), 1.408 MeV ( 7 2 ), 2.144 MeV ( 5 2 ), 2.211 MeV ( 9 2 ), 2.301 MeV ( 9 2 ) and 2.470 MeV ( 3 2 ). Some multipole mixing ratios were also determined. Comparison is made with the shell-model calculations of Ohnuma and Vervier.
