3Stellar reaction rate of 55Ni(p,γ)56Cu in Type I X-ray bursts显示文摘^56Cu is close to the waiting-point nucleus ^56Ni and lies on the rapid proton capture (rp) process path in Type I X-ray bursts (XRBs). In this work, we obtained a revised thermonuclear reaction rate of ^55Niep;cT56Cu in the temperature region relevant to XRBs. This rate was recalculated based on the recent experimental level structure in ^56Cu, the recently measured proton separation energy of Sp = 579.8(7.1) keV, together with shell-model calculation, and the mirror nuclear structure in ^56Co. The associated uncertainties in the rates were estimated by a Monte Carlo method. Our revised rate is significantly different from the recent results, which were partially based on experimental results;in addition, we found that a result in a previous work was incorrect. We recommend our revised rate to be incorporated in the future astrophysical network calculations.Shao-Bo Ma Li-Yong Zhang Jun Hu 2019Nuclear Science and Techniques2019,30,9:0
4Effects of Microscopic Three-body Forces in Asymmetric Nuclear Matter显示文摘The efiects of microscopic three-body forces on the equatioil of state(EOS)and the single particle properties of isospin asymmetric nuclear matter have been studied within Brueckner-Hartree-Fock framework~[1]The microscopic three-body force model constructed from meson exchange current approach in Ref.~[2] has been extended to isospin asymmetric nuclearZuo Wi U.Lombardo A.Lejeune J.F.Mathiot 2001IMP & HIRFL Annual Report2001,,1:0
5Study of Proton Resonances in ^(22)Mg by Resonant Elastic Scattering of ^(21)Na+p and Its Astrophysical Implication in ^(18)Ne(α,p) ^(21)Na Reaction Rate显示文摘Proton resonant states in 22Mg have been investigated by the resonant elastic scattering of 21Na+p. The 21Na beam with a mean energy of 4.00 MeV/u was separated by the CNS radioactive ion beam separator(CRIB) and bombarded a thick(CH2)n target. The energy spectra of recoiled protons were measured at scattering angles of θcm ≈172° and 146°,respectively. A new state at 7.06 MeV has been observed clearly and another new one at 7.28 MeV is tentatively identified due to its low statistics. The proton resonant parameters were deduced from an R-matrix analysis of the differential cross section data. The astrophysical resonant reaction rate for the 18Ne(α,p)21Na reaction has been estimated,and it is about five times larger than that assumed before.S.Kubono T.Teranishi M.Notani H.Baba S.Nishimura J.Y.Moon M.Nishimura S.Michimasa H.Iwasaki Y.Yanagisawa N.Hokoiwa M.Kibe J.H.Lee S.Kato Y.Gono C.S.Lee 2009原子核物理评论2009,26,S1:0
