Secondly , on the base of pairing correlation , the odd - even differences of nuclear qualities were researched systemically , then we educed the following three mostly research results . first , from the binding energy formula of the nuclear , fitted the nucleus experimental data of the a - 130 , 150 and 190 regions by using the odd - even differences formula of binding energy , the odd - even differences of binding energy were observed , it showed that even - even nucleus were steadier than neighboring odd - even ones and odd - even nucleus were steadier than neighboring odd - odd ones , this conclusion accorded with the experimental results 本文的重點是在對關(guān)聯(lián)的基礎(chǔ)上,系統(tǒng)地研究了原子核性質(zhì)的各種奇偶差,主要研究結(jié)果有以下三個方面: ( 1 )從原子核的結(jié)合能公式出發(fā),運用結(jié)合能奇偶差的公式,擬合a為130 , 150和190區(qū)的原子核的實驗數(shù)據(jù),可以看出結(jié)合能存在的奇偶差,表明偶偶核比相鄰的奇偶核穩(wěn)定,奇偶核比相鄰的奇奇核穩(wěn)定,得到了與實驗一致的結(jié)果。
Second , the moments of inertia were analysed meticulously , fitted the nucleus experimental data of the a - 130 and 150 regions by using the odd - even differences formula of the moments of inertia , it showed that there was n ' t obvious odd - even differences , while there was obvious odd - even differences in 190 region . these results indicated that pairing correlation in 130 and 150 regions were weaker than 190 region . this conclusion was consistent with the laboratorial one ( 2 )對轉(zhuǎn)動慣量進(jìn)行了較為細(xì)致的分析,運用轉(zhuǎn)動慣量奇偶差的公式,擬合a為130和150區(qū)的原子核的實驗數(shù)據(jù),可以看出130和150區(qū)并不表現(xiàn)出明顯的奇偶差現(xiàn)象,而190區(qū)的轉(zhuǎn)動慣量存在著奇偶差,說明130區(qū)和150區(qū)的對關(guān)聯(lián)比較弱,而190區(qū)的對關(guān)聯(lián)比較強,這個結(jié)論與實驗的結(jié)果也是一致的。
