如果把原子核內每顆核粒子的平均結合能又稱比結合能與質量數原子核中的質子和中子的總數繪製成圖右下圖,便可發現圖中曲線在質量數大約等於56即鐵原子核時到達最高點,即是鐵原子核的總體能量最低。In other words, the same amount of energy will be given off when stand - alone nucleons come together to form the nucleus. when the binding energy per nucleon is plotted against the mass number, i. e. total number of protons and neutrons in a nucleus ( the bottom right figure ), it is found that the curve peaks around the mass number 56, i. e. the iron nucleus
如果把原子核內每顆核粒子的平均結合能(又稱比結合能)與質量數(原子核中的質子和中子的總數)繪製成圖(右下圖) ,便可發現圖中曲線在質量數大約等於56 (即鐵原子核)時到達最高點,即是鐵原子核的總體能量最低。Results show that vp37 protein can bind single strand nucleic acid cooperatively and nonspecificallty, and the vp37 - ssrna complex was stable at high salt concentrations, suggesting vp37 is a possible mp. vp37 is the only protein characterized so far showing rna - binding ability in genus fabavirus
為了驗證vp37是否具有核酸結合能力,我們利用6his - vp37蛋白進行了核酸結合實驗,結果表明vp37是一種能非特異性結合單鏈核酸的蛋白;其在結合核酸時具有協同性; na ~ +的變化對其核酸結合能力影響較小。Binding energy per nucleon
每個核子的結合能The effective coupling constants including isoscalar and mesons and isovector and mesons in the rmf are extracted from the dbhf results in symmetric and asymmetric nuclear matter. two sets of effective interactions in the rmf approach are deduced by imposing a condition, where the dbhf scalar and. vector self - energy or scalar self - energy and binding energy per nucleon at each density and asymmetry parameter are reproduced, respectively
為了使我們提取的有效相互作用能夠準確地再現出dbhf計算的核狀態方程以及密度依賴的不對稱能,我們採用第二種萬法提取有效介子核子耦合常數,即要求在對稱核物質中,每個密度處ilif計算出的標量自能及總結合能與dbhf給出的標量自能及總結合能一致,提取出。Firstly the binding energies and the ground state energies of hydrogen impurity in a lens - shaped quantum dot ( gaas / inl - xgaxas ) under vertical magnetic field will be displayed. then how to use the nuclear spin as the quantum bit will be given
首先研究了垂直磁場下透鏡型量子點( gaas / in1 - xgaxas )摻入類氫雜質后基態能和結合能,然後討論了如何利用量子點中雜質核自旋構造量子位。A significant difference on the scalar self - energy and effective mass of neutrons in asymmetric nuclear matter, especially in neutron matter, is observed. the difference would result in an unreasonable sigh of the extracted effective couplings for isovector mesons
利用這樣的耦合常數在rmf近似下計算的核物質的結合能與dbhf結果會有偏離,因而得到的核狀態方程也會有偏離,如在飽和點處結合能有小於2的偏差。Most of researches were focused on the ground binding energies foe a = 5 - 17 with the same potential in the shell model, that some of the computation were consistent with their experimental values, others below the lower limit of them and others beyond the higher limit
在殼模型中,用統一的相互作用勢研究了核子數a = 5 - 17的超核的基態結合能,有部分超核計算值擬合實驗值,有的偏離較大。The stability of a nucleus can be described in terms of a number of parameters
原子核的穩定度可以用若干參數來描述,其中一個參數是核粒子的結合能。One such parameter is the binding energy of particles inside the nucleus, i. e. the nucleons
原子核的總結合能是指把原子核分開成為獨立核粒子所需的能量。The total binding energy of a nucleus is defined as the energy that would be required to separate the nucleus into separate nucleons
換句話說,獨立核粒子結合組成一個原子核,就會釋放出相等於該原子核的總結合能的能量。Especially, the overbinding of he and the disagreement of interaction of he and be appears in the calculation, which in the variational calculation for he and e. the theoretical result for be presents overbinding problem with the aa potential of single gassian shape which gives a very good fit to the experimental, while that of he is lower than the experimental value with the aa potential fitting the experimental moreover the introduction of the three - body ann potential does n ' t reduce the inconsistency of the interaction
特別是在a , he超核計算中出現過緊束縛問題,並且在從6he和; be的變分計算中,若採用擬合he結合能實驗數據所得的( ? )高斯勢,則理論計算a ? be結合能呈現束縛過緊;反之,採用擬合發be結合能實驗數據的aa三高斯勢,計算he的結合能又偏小。In this paper the ground state structure of the four - hypemucluei ^ he > " be * be and a c are studied by applying a5 / fe structure model and few - body theory method and compared with the results of the shell model and the a cluster model from the ground binding energy and r. m. s distances

本文的重點是在對關聯的基礎上,系統地研究了原子核性質的各種奇偶差,主要研究結果有以下三個方面: ( 1 )從原子核的結合能公式出發,運用結合能奇偶差的公式,擬合a為130 , 150和190區的原子核的實驗數據,可以看出結合能存在的奇偶差,表明偶偶核比相鄰的奇偶核穩定,奇偶核比相鄰的奇奇核穩定,得到了與實驗一致的結果。分享友人
