Erata

Unfortunately, a couple of small mistakes made it on to the print-ready versions of the ChiCD. We apologize for these errors and will correct them as soon as possible on the CD itself.

Version	Date	Description

Version 1.3	06.12.2002	Chapter 1.5 has a wrong solution of the exercise number 3. The correct value is V = 2.98 x 10-5 m³ = 29.8 ml. Chapter 2.4 conntains a mistake in the question number 1.b): The first arrow must be an alpha-decay. Chapter 6.6 has a wrong solution of exercise number 1.b). The reaction produces not 4 H₂O but only one of them.
