THE ANGULAR WAVE FUNCTION OF HELLIUM ION (4 2 He+) IN MOMENTUM SPACE AT n ≤ 3

Abstract

Helium Ion (4 2 He+) is an example of a hydrogenic atom, as it consists of 2 protons and 2 neutrons forming a nucleus and only has an orbital electron. In daily life, hydrogen atoms are widely used in human life. The electron wave function in hydrogenic atoms is a combination of the radial wave function and the angular wave function, which is a solution to the Schrodinger equation. The wave function can also be expressed in momentum space by performing Fourier transform of the wave function in position space. This study aims to determine the angular wave function of Helium Ion in momentum space and its probability density at n ≤ 3. The results showed that the angular wave function and electron probability density on the Helium atom have the same function and illustration as the hydrogenic atom both in position space and in momentum space
