论文摘要
The elastic scattering $^{12}$C(p,po) Excitation Function (EF) was measured in the energy range Ep =16 - 19.5 MeV with resolution about 10 keV by means of innovative approach - MSS - the Method of Spectra Superposition at the 14-angle Magnetic Spectrograph (Apelsin) at beam with an energy spread of about 200 keV from U-150 cyclotron of INP Ulugbek (Tashkent) of Science乌兹别克斯坦学院[1-8]。获得的EF具有与阈值和水平数据的精确一致性的异常范围[2,9-12]。在厚度为13 mg/cm2的12C自支撑靶标上进行了测量,在Apelsin中心的面积为1 cm2。 20步能量主持人控制了质子能量,提供了3.5 meV宽的EP间隔,没有回顾的回旋子和41米长的梁管上的所有离子镜。质子蛋白的能量分辨率沿所有焦平面均优于5 keV,在所有焦平面上,通过特殊设计的坐标敏感的气体混合物MWPC检测到颗粒产物,而两个粒子恰好是偶然的。该收购系统基于IBM PC在线,具有快速的CAMAC分支(在St-Petersburg PNPI设计),其快速TDC模块和其他快速电子产品可立即从MWPC中选择和积累。 NMR-Monitor系统稳定光谱仪的磁场为3ppm [1,9]。 12c(p,po)散射的EF具有许多与G.S.相对应的共鸣。和众所周知的产品核心水平。但是80%的异常没有任何解释。提出了一个新概念来解释所有未认识的异常。提出了两种表达式写作I和写作II,以解释与A13相量状态的种群相对应的未知峰。提出的解释的结果看起来非常有前途(图13)。提出的组合质量共振(CIR)的概念
The elastic scattering $^{12}$C(p,po) Excitation Function (EF) was measured in the energy range Ep =16 - 19.5 MeV with resolution about 10 keV by means of innovative approach - MSS - the Method of Spectra Superposition at the 14-angle Magnetic Spectrograph (Apelsin) at beam with an energy spread of about 200 keV from U-150 cyclotron of INP Ulugbek (Tashkent) of Science Academy of Uzbekistan [1-8]. The obtained EF has a reach structure of anomalies in precise agreement with thresholds and levels data [2,9-12]. Measurements were done on the 12C self-supporting target with thickness 13 mg/cm2 and an area of 1 cm2 in the center of Apelsin. The 20-step Energy Moderator controlled the proton energy, providing a 3.5 MeV wide Ep interval with no readjustment of cyclotron and all the ionic-optics on the 41-meter-long beam-pipe. Energy resolution of Apelsin for protons is better than 5 keV along all focal plane, where particle-product were detected by specially designed coordinate-sensitive gas mixture MWPC with two particle counters in coincidence. The acquisition system was based on IBM PC online with a fast CAMAC branch (custom designed at St-Petersburg PNPI) with fast TDC modules and other fast electronics providing immediate selection and accumulations of events from MWPCs. The NMR-monitor system stabilized spectrographs magnetic field to 3ppm [1,9]. The EF of 12C (p,po) scattering has many resonances that precisely correspond to g.s. and levels of well-known product-nuclei. But 80 percent of anomalies did not have any explanation. A new concept is proposed to explain all unrecognized anomalies. Two expressions Writing I and Writing II proposed to explain the unknown peaks which corresponds to population of A13 phase volume states. The results of the proposed explanation look very promising (Fig. 13). Concept of the Combinative Isobaric Resonances (CIRs) proposed
