刚刚看到一个题目的解答
可是我不了解它的物理意义
所以想请教各位版大~
题目:
A beam of spin-1 particles , moving along the y axis, is incident
on two collinear SG apparatues, the first with B along the z axis
and the second with B along the z' axis, which lies in the x-z plane
at an angle W relative to the z axis. Both apparatuses transmit
only the uppermost beams. What fraction leaving the first will pass
the second?
解答:
Jy
-i--- W
h(霸)
e |1 , 1> = ..................................
(1)我想请问这个Jy是什麽意思呢?
(2)我想请问|1 , 1>是什麽意思?
(3)这个运算式要表达的是什麽?
啊...对不起我真像个白痴
不过还请各位高手海涵赐教
不胜感谢呀^^"
