(d)Why a beam of silver atoms in its ground state is split into two separate b
eams in SternGerlach experiment?
【瓶颈】就这个实验发现，自旋为量子化的主因，想请问各位大大题目的原因是因爲一个
自旋向下和自旋向上，所以导致会有两个分开的beams吗，谢谢

1F：推 bethlehem: Because quantum state means electron is in mixtur 06/27 02:19
2F：→ bethlehem: e of states in which the amplitude of each state g 06/27 02:19
3F：→ bethlehem: ives the possibility of collapsing into such state 06/27 02:19
4F：→ bethlehem: after a measure as long as those states are eigen 06/27 02:19
5F：→ bethlehem: vector of the measurements operator.Before deflect 06/27 02:19
6F：→ bethlehem: ed by gradient magnetic field,a electron is about 06/27 02:19
7F：→ bethlehem: half to be spin-up and half to be spin-down.After 06/27 02:19
8F：→ bethlehem: the measurement,the outer most electron in silver 06/27 02:19
9F：→ bethlehem: atom collapse to either spin-up or spin-down purel 06/27 02:19
10F：→ bethlehem: y dependent on chance.So you could see two split c 06/27 02:19
11F：→ bethlehem: luster which contradictsled the original predictio 06/27 02:19
12F：→ bethlehem: n that there will be multiple clusters due to the 06/27 02:19
13F：→ bethlehem: magnetic dipole moment by angular moment then came 06/27 02:19
14F：→ bethlehem: the idea of intrinsic angular momentum called int 06/27 02:19
15F：→ bethlehem: rinsic spin. 06/27 02:19
