The Internuclear Separations And Wake Effcet Of H₂D⁺

It is a new field for fast molecular ion interaction with solid of the experimental and theoretical research,and it was developed in America,France and other countries in the 1980s.Although thousands of the neutral molecules's structure have been measured with conventional methods (such as photon absorb and emission). Because it is difficult to obtain these methods of molecular ions required bulk density, it can not be achieved by conventional methods.The H₂D⁺ is an important interstellar matter .The study for H₂D⁺ is an extremely high value for plasma physics, chemistry, objects astrophysics and micro dynamic. There is very little report on H₂D⁺, especially the report on three-dimensional chemical structure of H₂D⁺ .On the determination of the structure for the stereochemistry of H₂D⁺, Yang Bai-fang and others, who took advantage of the high-resolution atomic collision device of 720 Institute in SiChuan University In 1993.Obtained initially the Bond length of rHH and rHD, and got the isosceles triangle structure. Because the H₂D⁺ is mixed with D₂⁺ in experiments, those can not separated by the experimental device before Coulomb explosion. the D+ count will be effected by D₂⁺, so the measure about△EDD is not accurate, certainly the accuracy of rHH and rHD will be effected. I propose a new solution to solve this problem. I discuss the proportion of the formation of H₂D⁺ and D₂⁺ in the reaction channel in the laboratory conditions ,inferr the molar ratio of H₂D⁺ and D₂⁺ ions in the mixed, determine D₂⁺ on the contribution to H₂D⁺, Use the nonlinear fitting function of origin.The Gaussian distribution function is synthesized from the original spectrum, and then the contribution of D₂⁺ from a mixture of Gaussian distribution function is weed out .At last ,the pure D+ energy spectrum is synthesized. This improves the accuracy of△EDD. The feasibility of the program have demonstrated by the result. The result agree well with the measured result.The paper raises the possibility of structural theory about the H₂D⁺, and determine the correct model structure by calculating. The paper also raises the wake effects of the theory for H+ in terms of the H₂D⁺, before the theory was put forward on the HD₂⁺ three-body wake effects of the theoretical model by Zhu Zhou-sen and others in 2008, the structure of H₂D⁺ and HD₂⁺is very similar.The result isε=41.12eV, r_HD=0.940(A|°), r_HH=1.373(A|°)。...
