[en] High-spin states up to the F_7/2-shell band termination at Jπ=15+ have been observed for the first time in the odd-odd N=Z=23 nucleous ⁴⁶V. The new level scheme has two separate structures corresponding to spherical and prolate shapes. A rotational band has very similar energies to the yrast sequence in ⁴⁶Ti and is therefore assumed to be a T=1 configuration

[en] The analysis of new experimental data, rotor-plus-quasideuteron and shell model calculations for the odd-odd N = Z nuclei ⁴⁶V and ⁵⁰Mn is presented. Low-lying low-spin states exhibiting collective properties appropriate for the K = 0, K = 3, and K = 5 bands are identified. The strong isovector M1 transitions of quasideuteron origin in ⁴⁶V and ⁵⁰Mn are shown to be important indicators for collective features and perfectly fit into the systematics of M1 transitions in odd-odd N = Z nuclei.

[en] Activities of visiting researchers and students and experiments scheduled to be performed in the cyclotron are briefly reviewed. The branching ratio of an isospin-forbidden beta-decay branch from vanadium 46 has been found to be 50 ppm of the superallowed ground state branch

[en] The results for the odd-odd N=Z nucleus ⁴⁶V are presented

[en] Lifetimes of excited nuclear states are studied with a particular emphasis on the determination of nuclear lifetimes by means of the Doppler shift decomposition attenuation method - DSAM - which is based on the mathematical theory of stochastic processes; by its own nature, the emission of recoil nuclei, their motion through an amorphous medium and the detection of gamma rays resulting from these nuclei are all stochastic processes as well. Measurements of lifetimes together with other measurements can supply nuclear structure data, as well as information on the slowing-down process of an energetic ion through a certain material. The experimental tests have been carried out on the Tandem accelerator - IFIN, Bucharest. (author)

[en] Deformed configuration mixing shell model with isospin projection (DSMT) is applied to study the structure of collective T=0 and T=1 bands in the odd-odd N=Z nuclei ⁴⁶V and ⁵⁰Mn. The pf-shell KB3 interaction is employed in the calculations. The T=0 and T=1 bands in both the nuclei compare well with experiment including the E2 and M1 transition strengths. The DSMT predicted structures of the bands in these nuclei are similar to those in the rotor-plus-quasideuteron model
