Studies of (α, d) Reactions on N=28 Nuclei. II. 52Cr(α, d)54Mn

Abstract

Angular distributions of deuterons from the 52 Cr(α, d) 54 Mn reaction at E α =24 MeV have been measured and are analyzed in terms of the zero-range DWBA theory. Transferred angular momenta are assigned for 20 transitions up to 4.72 MeV excitation in 54 Mn. Strong transitions to the 0.363 and 4.715 MeV states in 54 Mn are interpreted as due to high angular momentum transfers, and these levels are assigned J π =5 + and 8 - , respectively. Seven L =0 transitions leading to E x =1.449, 1.623, 1.777, 1.913, 2.126, 2.873 and 3.835 MeV states in 54 Mn have been observed, and these levels are assigned as J π =1 + . The transition strengths for the low-lying states are discussed on the basis of a simple shell model and are found to be in good agreement with the shell model predictions.
