This work reports the first rotational bands observed in the neutron-deficient nucleus $$^{231}$$ 231 U. Excited states were populated in the $$^{232}$$ 232 Th($$\alpha $$ α ,5n) reaction at a beam energy of 52 MeV. Coincident decay $$\gamma $$ γ -rays were measured with the high-purity germanium detectors of the afrodite spectrometer array, in conjunction with a recoil detector to discriminate against the fission background. The bands are interpreted as the ground-state band $$\nu [633]5/2^{+}$$ ν [ 633 ] 5 / 2 + , yrast band $$\nu [752]5/2^{-}$$ ν [ 752 ] 5 / 2 - , and an excited band $$\nu [631]3/2^{+}$$ ν [ 631 ] 3 / 2 + . Configuration assignments are supported by Cranked Shell Model and B(M1)/B(E2) calculations. The excitation energy of the $$\nu [752]5/2^{-}$$ ν [ 752 ] 5 / 2 - bandhead is suggested to be 113.0 keV.

“…To expand the observed energy range during measurements from series 2, a matched resistive voltage divider was installed between the preamplifier and the digital pulse processor, reducing the output voltage of the preamplifier by a factor of 10. The energy calibration of the spectroscopic system in both cases was performed using X-ray and gamma lines from radioisotope sources of 207 Bi [30], 237 Np [31], and 241 Am [32]. The systematic uncertainty associated with calibration errors is the same for all measured distributions and does not exceed 2%.…”

Research of the ionization loss of 50 GeV protons, the path of which in the depleted layer of the silicon detector was smoothly regulated in the range from 0.3 to 10 mm, is presented. In the experiment, we used a flat silicon detector with a fixed thickness of the depleted layer of 300 μm. The smooth regulation of the path was realized due to the variation of the angle between the surface of the detector and the incident proton beam. The comparison of experimental data and theoretical calculations of the ionization loss demonstrates agreement in all range of thicknesses. Results of the research can be used in order to control the angle between the surface of the detector and the incident beam of relativistic particles. Besides, the results can be used in the analysis of data from astrophysical silicon detectors of charged particles if high-energy particles crossed flat detectors at arbitrary angle.
