[Wien] Whis are the differences between the cohesive energy and the formation energy of a compound?

[Z.J.]

Hi, well-beloved prof. Blaha and wien2k users,
    What are the main differences between the cohesive energy and the
formation energy of a compound? In some papers, the authors think the
cohesive energy is the same as the formation energy in physical meaning. But
in other papers, the authors think the two physical concepts are different
in physical meaning, saying Acta Materialia 50 (2002) 3301-3315. Which is
right? Any comments are appreciated. Thank you in advance.
    Best regards.

Yours sincerely,

                                 Ronald
