Homework Statement


The electron in a hydrogen atom occupies the combined spin and position staate

R_{12}\left(\sqrt{1/3}Y^0_lX_++\sqrt{2/3}Y^1_1X_-\right)

(a) If you measured the orbital angular momentum squared (L^2), what values might you get, and what is the probability of each?

(b) Same for the z component of the orbital angular momentum (L_z).

Homework Equations


We know that:
L^2\psi=h^2l(l+1)\psi\hspace{2cm} (1)

and

L_z\psi=hm\psi.

The Attempt at a Solution


(a)
So, given (1), i was thinking that the values that we might get are

2\sqrt{1/3}h^2, \mbox{ and } 2\sqrt{2/3}h^2.

I wasn't sure how to deal with the R_{12}.

I would appreciate if someone would give me a hint on how to get started.

Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
The value of H equals ## 10^{3}## in natural units, According to : https://en.wikipedia.org/wiki/Natural_units, ## t \sim 10^{-21} sec = 10^{21} Hz ##, and since ## \text{GeV} \sim 10^{24} \text{Hz } ##, ## GeV \sim 10^{24} \times 10^{-21} = 10^3 ## in natural units. So is this conversion correct? Also in the above formula, can I convert H to that natural units , since it’s a constant, while keeping k in Hz ?
