Nuclear track emulsion is exposed to a beam of radioactive 8He nuclei with an energy of 60 MeV and enrichment of about 80% at the ACCULINNA separator. Measurements of 278 decays of the 8He nuclei stopped in the emulsion allow the potential of the α spectrometry to be estimated and the thermal drift of 8He atoms in matter to be observed for the first time. 相似文献

The spectrum of 10He was studied by means of the 3H(8He, p)10He reaction at a laboratory energy of 25 MeV/A and small center-of-mass angles. Missing mass spectrum of 10He was derived from the obtained p-8He coincidence. A resolution of 0.7 MeV was achieved in this spectrum for the measured 10He energy. Most likely, a well isolated group of 10 events detected between 2 and 5 MeV and showing a maximum at about 3 MeV
in the spectrum of the present work exhibits the 10He g.s. resonance. 相似文献

The ACCULINNA-2 separator is intended to provide beams of exotic nuclei with Z = 1?30, energies of 10?C50 MeV/amu, and intensities that allow one to study excitation spectra and decay dynamics of neutron- and proton-drip nuclei. Examples from studies of the 10He and 6Be nuclei are presented. 相似文献

Complete fusion (CF) and incomplete fusion (ICF) reactions were studied for the cases of the loosely bound 6He and 6Li projectiles bombarding 166Er and 165Ho targets at energy of about 10 MeV/nucleon. Experiments were carried out to test an approach exploiting the measured intensities of ?? rays emitted at the transitions between the yrast-band levels of reaction products formed after the termination of neutron evaporation. Partial waves feeding the CF reactions 165Ho (6Li, 5 n) 166Yb and 166Er(6He, 6 n) 166Yb as well as ICF 165Ho (6Li, ??3n) 164Er and 166Er(6He, ??4n) 164Er reaction channels were revealed from the obtained ??-ray data. The method of exit channel identification via the triple coincidence (??1-??2-light charged particle) was employed for these reactions study. 相似文献

Momentum correlations inherent to the 6He constituents in the ground state of this nucleus were studied in the quasi-free scattering (QFS) reaction 4He(6He, 2α)2n at 6He beam energy of 25 MeV/nucleon. A detailed study of nucleus structure was performed for the first time in QFS reactions with an unbound spectator. The Plane Wave Impulse Approximation was used in analyzing the experimental data. It was shown that the experimental data are described by model calculations in which the two neutron final state interaction is taken into account. t + t and t + d + n configurations were also studied in the 4He(6He, tα)t and 4He(6He, tα)dn QFS reactions. 相似文献

A study was carried out on the dependence of the optical properties such as the maxima in the absorption and luminescence
spectra, Stokes shift, and quantum yield on the composition of the three-component Cd2+—L-Cys—S2− reaction system under synthesis conditions at 298 ± 2 K and pH 7. Equations describing the dependence of the position of
the maximum in the luminescence and absorption spectra of solutions on their composition were obtained by mathematical planning
using the Scheffe simplex-lattice design and treatment of the data. The region of compositions for unstable colloidal solutions
was determined. 相似文献

Low-energy spectra of the 8, 10He nuclei were investigated in the (t, p) -type reactions at small centre-of-mass angles using ~ 25 AMeV beams of 6He and 8He nuclei. The 0+ ground state (g.s.) of 8He and excited states, 2+ at 3.6-3.9MeV and (1+) at 5.3-5.5MeV, were populated with cross-sections of 200, 100-250, and 90-125μb/sr, respectively. To account for a near-threshold anomaly observed in the 8He spectrum the population of a 1- continuum (soft dipole excitation) was considered. The lowest-energy group of events in the 10He spectrum was observed at ~ 3 MeV with a cross-section of ~ 140 μb/sr. This result is consistent with the previously reported observation of 10He providing a new g.s. position for 10He at about 3MeV. 相似文献

The collective resonant photoresponse in Si/SiGe structures with a 2DEG under microwave radiation is reported for the first time. The application of microwave radiation of various frequencies results in resonant photoconductivity at magnetic field values that are systematically lower than expected for the cyclotron resonance (CR) in an infinitely large two-dimensional electron system. The analysis of the data shows that the observed microwave radiation induced response is dominated by plasmon excitations. 相似文献
