Abstract
The high-spin structure of 137Nd has been studied through the 110Pd(30Si,3n) and the 123Sb(19F,5n) reactions at beam energies of 125 and 97 MeV, respectively. A very complex level scheme has been established up to spin View the MathML source and 23.9 MeV of excitation energy. Regular bands are observed at high-spin, consisting of either M1 and E2 crossover transitions, or of stretched M1 or E2 transitions. Calculations have been performed in the framework of the interacting boson-fermion model with broken pairs for the relatively strong ΔI = 1 regular structures observed above spins View the MathML source and View the MathML source, which are well described by the View the MathML source and View the MathML source configurations, respectively.
