摘要:
根据超强磁场下朗道能级量子化的近似修正并结合原子核壳层模型,我们详细计算了在不同磁星表面(密度ρ/μe=5×108mol/cm3,磁场B:4.414×1013G-4.414×1017G,温度分别为T=5×108K,T=1×109K和T=5×109K)Mn的三个同位核素的核反应52Mn→52Cr,53Mn→53Cr和54Mn→54Cr的电子俘获率.结果表明,Mn的三个同位核素在同一温度,密度和磁场的电子俘获是有所不同的(同种元素的核内核子轨道不同排布情况对电子俘获有影响),随着磁场增大(4.414×1013G-4.414×1017G),这种差异会变得越来越小;磁场(4.414×1013G-4.414×1017G)对其电子俘获的影响相当显著,最高能增加4个数量级;温度对其的电子俘获也有一定影响,但影响不大.
Abstract:
According to landau level quantized approximate correction in the strong magnetiv field and combined with nuclearshell model,we calculated the detailed electronic capture rates at different magnetar surfaces. ( density ρ/μe = 5 ×108 mol /cm3,magnetic field B: 4. 414 ×1013 G ~ 4. 414 ×1017G, temperature were T = 5 ×108k,T = 1 ×109k and T= 5 ×109 k) of the three Mn isotope nuclides ’nuclei reactions 52Mn →52Cr, and 52Mn →53Cr and 54Mn → 54Cr. Theresults show that electron captures of the three Mn isotope nuclides at the same temperature, density and magnetic fieldare different ( the same nuclide in nuclear nuclear track different configuration of electron capture influential) . Alongwith increasing magnetic field ( 4. 414 ×1013 G ~ 4. 414 ×1017G), the difference will become smaller. Magnetic fieldseffeit ( 4. 414 ×1013G ~ 4. 414 ×1017G) on the electron capture is quite significant. Temperature also have certain effecton the electron capture, but the impact is not abvious.
