| Apr 24, 2023 at 22:18 | comment | added | Ghoster | Does this minus sign impact the calculations in any way? Yes. It makes them give sensible (i.e., finite) results. | |

| Apr 24, 2023 at 18:06 | comment | added | Zorbakk | I just edited my post: the wave function did indeed contain a minus sign in the exponential. I must've missed it while writing this post somehow. Does this minus sign impact the calculations in any way? | |

| Apr 24, 2023 at 17:32 | comment | added | Ghoster | Are you sure the wave function wasn’t specified as $Ne^{-\gamma r}$? As written, the problem doesn’t make sense. | |
| Apr 24, 2023 at 16:49 | comment | added | FlatterMann | While answers of the form "plane waves are not normalizable" are technically correct, you still have to learn how to deal with plane waves because they are actually far more important in physics than bound solutions. See e.g. physics.stackexchange.com/q/165373 for a few pointers of how to deal with the problem. The "obsession" of non-relativistic quantum mechanics with finite, nicely normalizable systems is more of an educational artifact: it's relatively easy to teach compared to the real problem. | |
