Karazin popup.description2 The level structure of 46Тi has been studied through the non-selective 45Sc(р,?) reaction in the proton energy range Ep=1.2 - 3.1 MeV. The average resonance proton capture method has been applied to spin-parity assignments for states up to 5.5 MeV excitation energy in 46Тi. The radiative strength function of primary E1-transitions, populating these states has been determined. The data so obtained are compared with predictions of various models. Comparison with 50Cr, a cross-conjugate nucleus of 46Тi, is also made. The observed states are interpreted within the frame of large scale shell model calculations in the full pf space (positive parity) and as particle-hole excitation from the d3/2 shell (negative parity). For naturale parity states of 46Тi, experimental data and shell model results are compared with those of the interacting boson model. The best description for E1 transitions is achieved on the base of the model accounting for the dependence of the strength function on the ?-ray energy, temperature, and nuclear shell structure. The results of the experiment searching for 2K-capture with large low-background proportional counter are presented. The comparison of spectra of the background of the pro-portional counter filled with Kr enriched in 78Kr (8400 hr) and with natural Kr (4500 hr) is given. A new limit on the half-life of 78Kr with regard to 2K-capture, _l/2 yrs (90% C.L.), is obtained,. Product Description popup.authors popup.nrat_date 2020-04-02 Close
