BeCl_2分子的低能电子弹性散射研究 Title:InvestigationofLow-EnergyElectronElasticScatteringbyBeCl2Molecules Abstract: Inrecentyears,thestudyofelectron-moleculeinteractionshasgainedsignificantattentionduetoitsimportanceinmanyfields,includingastrophysics,materialsscience,andquantumchemistry.Inthispaper,wefocusoninvestigatingtheelasticscatteringoflow-energyelectronsbyBeCl2molecules.Thegoalistounderstandthebehavioranddynamicsoftheseinteractions,providingvaluableinsightsintothefundamentalprocessesinvolved. Introduction: Theelasticscatteringoflow-energyelectronsbymoleculesplaysacrucialroleinvariousphysicalandchemicalphenomena.Thescatteringprocessprovidesinformationaboutthemolecularstructure,bonding,andelectronicproperties.Italsoprovidesinsightsintotheelectron-moleculeinteractionpotentialsandtheirimplicationsinawiderangeofapplications. Methodology: Tostudytheelasticscatteringoflow-energyelectronsbyBeCl2molecules,weemploythequantummechanicalscatteringtheory.WeutilizeadvancedcomputationaltechniquessuchasthepartialwaveanalysisandtheBornapproximationtodeterminethescatteringcross-section,phaseshifts,anddifferentialcross-sections.Thesequantitiesprovideadetaileddescriptionofthescatteringprocessandhelpunderstandtheunderlyingdynamics.
