Kajian kualitatif kekuatan pegas (Oscillator Strength) dan tingkat energi transmisi menggunakan Metoda Hartree-Fock

Abstract

Tingkat-tingkat energi pada transisi atom berelektron banyak diformulasikan melalui pendekatan antisimetri fungsi gelombang masing¬masing aras transisi menggunakan metoda Hartree-Fock dengan menerapkan fungsi gelombang elektron-elektron individual penyusun atom. Perhitungan nilai kekuatan pegas f (Oscillator Strength) pada transisi yang diijinkan dapat dilakukan dengan diketahuinya fungsi gelombang masing¬masing aras transisi tersebut. Aplikasi metoda Hartree-Fock telah digunakan dalam penentuan nilai f dan tingkat-tingkat energi pada transisi aras dasar 1s2----1s2p atom helium. Kate kunci: metoda Hartree-Fock, tingkat energi transisi, nilai kekuatan pegas f. The energy levels of multielectron atomic transitions were formulated by approximation of antisymmetrized wave function of each transition states using Hartree-Fock method by applying the wave functions of each individual electrons of the atoms. The calculation of oscillator strength V value) of allowed transitions can be done by deriving the wave function of each states. The Hartree-Fock method has been applied to the determination of f value and the energy levels of helium first ground state transition 1s2 —1s2p. Keywords: Hartree-Fock method, transitions energy levels, oscillator strength (Jvalue). xix This document is Undip Institutional Repository Collection.
