[Pw_forum] About ld1.x

[robert.guzman]

Dear users of QE.

I was reading  a web page 
(http://phya.snu.ac.kr/~nmcuong/board/physics/INPUT_LD1.html) where 
explain the keys of ld1.x code. In the last part of this web page, 
appears references, but I am thinking that the last reference is 
incorrect because I could not find it. It is PRB 55, 191 (1997). Someone 
know which is the correct reference.

Best Regards.
