principal investigator – I instigated the research, raised the necessary funds, and/or was awarded the neutron beam time, designed the experiments, was involved in some experimental work carried out and/or advised on data analysis. I managed the project including instruction of Post-Docs and Ph.D. students. I was responsible for writing the paper, submitting it to the journal and responding to Referees’ comments.

equal contributor – The research was a collaboration between different groups, financial inputs, research tasks, and author responsibilities were shared. The level of contribution varies on a case-by-case basis, and so it is reasonable to apportion the effort equally between all authors.

normal type face – other authors were the major contributors
