Kurguz I. Characteristic of the magnetic dipole resonance in odd nuclei of the 2s1d-shell

The thesis is aimed to the study of magnetic dipole resonance characteristics, nucleon pairing influence on the center-of-gravity position and on the behavior of a total M1-resonance force in odd nuclei of the sd-shell. The function of the excitation reaction of radiation proton capture by nuclei 22Ne, 26Mg, 30Si, 34,36S in the range of accelerated proton energy Ep=0,8-3,0 MeV is determined. The spectra and angular distributions of gamma-quanta, generated due to the disintegration of the highest-intensity resonances, which form the resonance-like structures existing in the (p,gamma)-reaction, are measured. Gamma-decay of the resonance-like structures, taking place in the reactions of radiation proton capture by the nuclei 22Ne, 26Mg, 30Si, 34,36S, 38Ar is studied. The M1-resonance is identified on the ground and excited states of nuclei 23Na, 27Al, 31P, 35,37Cl and the position of their centers of gravity in nuclei are defined more exactly. In the nuclei 39K the M1-resonance is identified for the first time and the center-of-gravity position is determined. The nucleon pairing influence on the center-of-gravity position of the M1-resonanse in the odd nuclei of the sd-shell is shown. The total force of the M1-resonance in above-mentioned nuclei is determined. It has been established that the behavior of this force corresponds to that, obtained from analysis of the Kurat sum rule (within the framework of the shell model)
