Observation of the bond-dependent Doppler broadening of the p(15N, αγ)12C nuclear reaction

Excitation curves for the p(¹⁵N, αγ)¹²C nuclear reaction have been measured on a number of hydrogen-bearing gases to investigate the bond-dependent Doppler broadening resulting from the motion of the target hydrogen atoms. Contributions to the resonance width due to the intrinsic width of the resonance, gas-induced beam energy loss and energy straggle, accelerator beam energy spread, and Doppler broadening are considered. Calculations of Doppler broadening based on molecular spectroscopy data are presented.     

The ~(11)C(p, g)~(12)N Reaction Rate and the Conversion of ~3He Into CNO

The reaction sequence of 3He(a, g)7Be(a, g)11C(p, g)12N to CNO could be an alterative way to convert 3He into CNO instead of 34He 12C. It may become important in some specific environments, such as in the very massive stars with low multiplicity. Whether …     

The Evaluation and Calculation of Production Cross Sections for ~(11)C, ~(13)N and ~(15)O from ~(11)B, ~(13)C, ~(15)N(p,n) and ~(16)O(p,x)~(13)N Reactions up to 80 MeV

Introduction The medical radioisotopes are used for diagnostic and therapeutic purposes, as well as metabolism and physiological function researches in modern medicine. If a short-lived radioisotope emits a predominant or single γ-rays of 60～300 keV, it is of greater advantage since single photon emission computed tomograph(SPECT) can be performed; similarly β~ emitters are also of great significance since three dimensional high resolution scans can be obtained via
