The wave functions and form factors of E1 excited states of the deformed nucleus 24Mg are obtained within the particle-core coupling version of the shell model by using spectroscopic data on direct nucleon-pickup reactions. A comparison of the calculated E1-strength distributions with experimental cross sections shows the validity of the theoretical approach used, which is based on connections between direct and resonance nuclear reactions.

On the basis of spectroscopic information about direct pickup reactions, the multipole magnetic resonances M2, M4, and M6 of the 26Mg nucleus are calculated within the particle–core coupling version of the multiparticle shell model. The excitation-energy distribution of the form factors for the multipole magnetic 1hω resonances is obtained for momentum transfers to a nucleus up to 2 fm–1. A comparison of the results of the calculations for the M6 form factors with corresponding experimental data confirms that the adopted model approximations are realistic.© 2005 Pleiades Publishing, Inc.
