Wave function collapse

  • #1
consider a atom who's single electron is made to jump into conduction band ,after some time the electron will come into it's valence band by releasing the quanta of energy but if an observer observes the electron in it's excited state continuously it's wave function will collapse to bring about the electron in that state
therefore the atom can exist in that state(non stable) for a long period (as per observation),which resists the electron to come into valence band again?

This is called the "quantum zeno effect". You can effectively prevent an atom from decaying by repeatedly observing it (really really fast).
