High - resolution two - proton stripping to 2 p - 1 h 7 / 2 − states via the 59 Co ( 3 He , n γ ) 61 Cu reaction
نویسندگان
چکیده
The challenge of achieving high resolution in binary reactions involving an outgoing high-energy neutron is solved by detecting the γ-ray decay of populated excited states in an array of escape-suppressed HPGe detectors in coincidence with fast neutrons. The selectivity of the arrangement is of the order of 1 in 1000 and is demonstrated by L = 0 two-proton stripping to 7/2− 2p-1h levels using the Co(He,nγ)Cu reaction at Elab = 22.5MeV. The observed relative two-proton stripping strengths are compared with large-basis shell-model calculations.

The total cross sections of the processes He(γ, p)H and He(γ, n)He are calculated. For these exclusive reactions we investigate the question of the giant dipole peak height, but we also consider higher energies. The calculation includes full Final State Interaction (FSI) via the Lorentz Integral Transform (LIT) approach [1] and employs the semi-realistic MTI-III potential [2]. The LIT method ha...

DFT(B3LYP) studies on first protonation step of a series of Cu(II) complexes of some tripodal tetraamines with general formula N[(CH(2))(n)NH(2)][(CH(2))(m)NH(2)][(CH(2))(p)NH(2)] (n = m = p = 2, tren; n = 3, m = p = 2, pee; n = m = 3, p = 2, ppe; n = m = 3, tpt; n = 2, m = 3, p = 4, epb; and n = m = 3, p = 4; ppb) are reported. First, the gas-phase proton macroaffinity of all latter complexes ...

The behaviour of the i 13/2 and h 9/2 single-neutron strength was studied with the (α, 3 He) reaction on 138 Ba, 140 Ce, 142 Nd and 144 Sm targets at a beam energy of 51 MeV. The separation between the single-neutron states i 13/2 and h 9/2 was measured in N =83 nuclei with changing proton number. To this end spectroscopic factors for states populated in high-ℓ transfer were extracted from the ...
متن کاملThe Effect of Cu Impurity on the CO-dissociation Mechanism on the Fe (100) Surface: A Full Potential DFT Study
In this study, the theoretical calculations of CO dissociation were carried out on Cu-Fe alloy surface by a full-potential method, which made more accurate results especially on the prediction of adsorption energies. This process may be governed by either a direct route or a H-assisted via HCO and COH intermediates pathways. In comparison to the pure surface Fe (100), the presence of Cu atom en...
