Jetter, C. J. McHargue and R. O. Williams, J. Appl. Phys. 27, 363 (1956).</mixed-citation> </citation-alternatives> </ref>\[/code\]but in other cases the input is : \[code\]1. L.T. Jetter, C. J. McHargue and R. O. Williams, J. Appl. Phys. 27, 363 (1956). \[/code\]and the output is: \[code\]<ref id="1"> <label>1</label> <citation-alternatives> <mixed-citation>L.T. Jetter, C. J.
