Erratum to ‘‘L X-ray intensity ratios for proton impact on selected rare earth elements” [Nucl. Instr. and Meth. B 261 (2007) 153–156] Sam J. Cipolla Physics, Creighton University, 2500 California Px., Omaha, United States

Eq. (3) should read:

ðLi =Lj Þtheory N  V V ¼ ¼1 ¼1p N N ðLi =Lj Þexp which is interpreted as giving, for example,

ð3Þ ðL‘ =La Þtheory ðL‘ =La Þexp

ðL Þexp

theory

since it

is assumed that L‘ (L3M1) X-rays do not suffer multiple ionizations of the M1 sub-shell. For extra clarity, therefore, the second sentence of Section 4 should read:

Fig. 1 shows that the L‘ =La versus Z theory to experiment ratios, as interpreted from Eq. (3), are generally between unity and 0.9 as Z increases, except for 0.81 ± 0.07 at Tm (Z = 69). This erratum does not affect the outcome or the conclusion presented in the paper. It only serves to clarify the analytical procedure.
