# Bound vs not bound states

Bound vs "not"bound states

## Homework Statement

Hi, I do not understand how two bound state wavefunctions differ from not bound state
wavefunctions.
To be more precise I m thinking about the graphical representation.

ons[/b2. Relevant equati

## The Attempt at a Solution

I speculate that bound states can overlap or get close to each other.
Perhaps the problem is in meaning of "bound" in this particuular case?
Could someone help me to understand this better?
