The Iraqi Journal of Physics operates a double-blind peer review policy followed by the instruction of COPE. Authors may suggest potential reviewers if they wish; however, the decision to consider these reviewers is at the editor’s discretion. Authors who wish to suggest peer reviewers can do so in the cover letter and should provide institutional email addresses where possible or information that will help the editor verify and identify the potential introduced reviewers (for example, an ORCID or Scopus ID). Authors may request the exclusion of individuals as peer reviewers, but they should explain the reasons in their cover letter on submission. Authors should not exclude too many individuals, as this may hinder the peer review process. Please note that the editor may choose to invite excluded peer reviewers. Intentionally falsifying information, for example, suggesting reviewers with a false name or email address, will result in the rejection of the manuscript and may lead to further investigation in line with our misconduct policy.
