【摘要】 本文对氮川丙酰胺（NTP）经⁶³Coγ射线辐照生成的自由基和陷落电子的电子自旋共振（ESR）波谱进行了研究。（1）提出了γ辐照NTP多晶、单晶的ESR谱及模拟谱。初步认为,分裂的18条谱线是γ辐照NTP自由基所引起,对称的“S”形谱线是γ辐照生成的陷落电子所引起。（2）给出了γ辐照NTP谱线强度的升温和恒温衰减曲线。发现NTP自由基在100℃以下温度稳定存在,自由电子在150℃以下温度稳定存在,当温度接近NTP熔点（186℃）时,ESR谱线强度快速衰减到零。（3）认为该谱是由NTP自由基和晶格缺陷中的陷落电子两部分谱线迭加而成。更多还原

【Abstract】 This paper presents an ESR spectroscopy studied on free radicals and free electrons trapped in γ-irradiated NTP crystal.(1)The spectra of γ-irra-diated NTP polycrystal and singlecrystal were obtained and their simulated (model) spectra are suggested.It is preliminarily proposed that 18 hyperfine are caused by radicals trapped in γ-irradiated NTP crystal and that the "S" shaped symmetric spectrum is caused by free electros trapped in γ-irradiated NTP lattice dafect. (2)The decaycurves of the signal intensity of γ-irradiated NTP polyorystal with inoreasingtemperature and at constanttmperature are given. It is found that the radicals trapped in γ-irradiated NTP crystal are stable below 100℃ which the free electrons trapped in γ-irradiated NTE lattice defects are stable below 150℃. When the temperature was near the melting point of NTP (186℃), the signal intensity decayed rapidly to zero. (3) It is considered that the signal intensity of the system resulted from the superposition of signal intensity of NTP radicals and free electrons trapped in the lattice defects.更多还原
