In thenatSn+20Ne (164,196 MeV) reactions gamma-ray spectra were observed in coincidence with fast alpha particles forward peaked and with those evaporated into a backward hemisphere. The observed differences in the form of the gamma-ray spectra and in the corresponding yields of high-energy gamma-rays are preliminary related to the time evolution of the deformation of the nuclear systems formed in the heavy ion induced fusion reaction. 相似文献

Experimental excitation functions are presented for 45Sc(d, p)46Sc, 45Sc(d, t)44Sc, 45Sc(6He, 5He*)46Sc and 45Sc(6He, α)47Sc reactions at projectile energies near the Coulomb barrier. The obtained excitation functions for reactions 45Sc(d, p)46Sc and 45Sc(6He, 5He*)46Sc have similar behavior and have a maxima near the Coulomb barriers of these reactions. The compilation of the available experimental data, obtained at deuteron- and 6He-energies near the Coulomb barrier, showed that the values of the cross sections at the maxima of the excitation functions obtained in (d, p) reactions and the reactions for one-neutron pickup from the 6He projectiles have a different Z-dependence. 相似文献

High-spin states of the 22Ne nucleus in the excitation energy range of 15–30 MeV have been studied. The angular correlation method has been used to determine the spins of excited states. A number of new states with high angular momenta—20.0 MeV (9?), 20.7 MeV (11?), 21.6 MeV (9?), 22.2 MeV (12+), and 25.0 MeV (9?)—have been revealed. They are intensely populated in the reaction 14C(12C, α1)22Ne* → α2 + 18O and correspond to the rotational bands of various structures. 相似文献

We consider theoretical motivations to search for extra short-range fundamental forces as well as experiments constraining their parameters. The forces could be of two types: 1) spin-independent forces; 2) spin-dependent axion-like forces. Different experimental techniques are sensitive in respective ranges of characteristic distances. The techniques include measurements of gravity at short distances, searches for extra interactions on top of the Casimir force, precision atomic and neutron experiments. We focus on neutron constraints, thus the range of characteristic distances considered here corresponds to the range accessible for neutron experiments. 相似文献

The crystal structure of tripotassium sodium hexachloroferrate(II) has been determined by X‐ray diffraction at 293, 84 and 9.5 K. The accurate and extensive data sets collected should be suitable for charge–density analysis studies. 相似文献
