THE EFFECT OF THE ATOMIC OR MOLECULAR STRUCTURE ON Z-OSCILLATION OF ELECT RON-STOPPING POWER

  • 摘要: 本文在Firsov理論基礎(chǔ)上,引入Slater波函數(shù)等概念,解釋了原子結(jié)構(gòu)對(duì)Se(E)的Z振蕩的影響。它不僅能解釋常規(guī)能量范圍內(nèi)(101000keV)的輕元素靶和重元素靶的Z振蕩行為,而且能解釋更高的能量范圍內(nèi)(10100MeV)Z振蕩行為。本文引用了分子軌道法理論來(lái)處理分子靶問(wèn)題,導(dǎo)出了分子結(jié)構(gòu)對(duì)Se(E)的Z振蕩影響的方程式,使能處理相當(dāng)寬的能量范圍內(nèi)的分子靶的Se(E)的Z振蕩問(wèn)題。應(yīng)用本文方法所得結(jié)果與Z1C和Li+Z2靶的Z1(或Z2)振蕩的實(shí)驗(yàn)結(jié)果進(jìn)行了比較,同時(shí)還與在較高能量范圍的S+Na和F+Ag系統(tǒng)的實(shí)驗(yàn)結(jié)果作了比較,都得到了滿意的結(jié)果,說(shuō)明本文提出的方法是令人滿意的。
    Abstract: Based on Firsov theory (1959), the concept of the Slater wave function etc. is introduced, then the equation of the effect of atomic structure on Z-oscillation of Se(E) is derived. And by using the molecular orbital theory, the equation of the effect of the molecular structure on Z oscillation of,Se(E) is obtained. These obtained equatio nare suitable for light or heavy element target not only in the lower energy range (10-1000 keV), but also at the higher energy.The results calculated with these equations for Z1C and Li+Z2 in the lower energy range, S+Na and F+Agin the higher energy range, and H+-CdTe all are in good agreement with the experimental ones given in the literatures.
