Preface

These are my own solutions to the problems in Introduction to Quantum Mechanics, 2nd ed. I have made every
effort to insure that they are clear and correct, but errors are bound to occur, and for this I apologize in advance.
I would like to thank the many people who pointed out mistakes in the solution manual for the first edition,
and encourage anyone who finds defects in this one to alert me (griffi). I’ll maintain a list of errata on
my web page (http://academic.reed.edu/physics/faculty/griffiths.html), and incorporate corrections in the
manual itself from time to time. I also thank my students at Reed and at Smith for many useful suggestions,
and above all Neelaksh Sadhoo, who did most of the typesetting.
At the end of the manual there is a grid that correlates the problem numbers in the second edition with
those in the first edition.

Chapter 1

The Wave Function

Problem 1.1
(a)

·j×2 = 212 = 441.

1 Σ 2 1
·j 2 × = j N (j) = (142 ) + (152 ) + 3(162 ) + 2(222 ) + 2(242 ) + 5(252 )
N 14
1 6434
= (196 + 225 + 768 + 968 + 1152 + 3125) = =
459.571.
14 14

j ∆j = j − ·j×
14 14 − 21 = −7
15 15 − 21 = −6
(b) 16 16 − 21 = −5
22 22 − 21 = 1
24 24 − 21 = 3
25 25 − 21 = 4


1 Σ 1
σ2 = (∆j)2 N (j) = (−7)2 + (−6)2 + (−5)2 · 3 + (1)2 · 2 + (3)2 · 2 + (4)2 · 5
N 14

= (49 + 36 + 75 + 2 + 18 + 80) = =
18.571.
14 14

√
σ = 18.571 = 4.309.

(c)
·j 2 × − ·j× 2 = 459.571 − 441 = 18.571. [Agrees with (b).]
