4-7 A Debye-Scherrer pattern of tungsten (BCC) is made with Cu Ka radiation. The

first four lines on this pattern were observed to have the following 8 values:

Line tl - -

1 20.3"

2 29.2

3 36.7

4 43.6

Index these lines (i.e., determine the Miller indices of each reflection by the use of Eq.

(3-10) and Appendix 10) and calculate their relative integrated intensities.
