Abstract
High-spin states in ⁴⁵Sc, ⁴⁵Ti and ⁴³Ca were studied by means of multiple $\gamma$ - and $\gamma$ -recoil-coincidences with the use of the GASP array and the Recoil Mass Spectrometer. The nuclei were populated in the 60 MeV ¹⁸O + ³⁰Si reaction. For the DSAM lifetime measurement the ³⁵Cl + ¹²C reversed kinematics reaction was used. In the article, a complete description of the experimental techniques used in course of the performed experiments is presented. The level schemes and the detailed information on the observed state properties, including B(M1) and B(E2) transition rates are inserted as well as their shell model interpretation.
