ABSTRACT
The nonrelativistic Schrödinger equation for a free particle can be obtained by replacing E by iħ(∂/∂t) and p by (ħ/i)∇in the nonrelativistic equation () p 2 2 m = E https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429493645/749bab20-4a79-4f5a-8c66-d9e9a36a87b9/content/eq1634.tif"/>
