| Popis: | A review of the theoretical studies of the 44Ti nuclear spectrum is given. In this example the diversity of nuclear degrees of freedom in complex nuclei and coexistence of excitation of different nature are demonstrated. The main attention is paid to the cluster model 40Ca + α and the shell model. In the latter case the calculation result and the detailed analysis of the role of nucleon pairing are presented. Similarities and differences in the spectra obtained in these approaches are considered. Rotational states and states of the molecular type are also briefly discussed. It is shown that many properties of the spectrum can be reasonably described in various models, which, therefore, are not completely independent and express the same physical phenomena in some cases. |
