摘      要：A researcher collaborating with many groups will normally have more papers (and thus higher citations and h-index) than a researcher spending all his/her time working alone or in a small group. While analyzing an author s research merit, it is therefore not enough to consider only the collective impact of the published papers, it is also necessary to quantify his/her share in the impact. For this quantification, here I propose the I-index which is defined as an author s percentage share in the total citations that his/her papers have attracted. It is argued that this I-index does not directly depend on the most of the subjective issues like an author s influence, affiliation, seniority or career break. A simple application of the Central Limit Theorem shows that, the scheme of equidistribution of credit among the coauthors of a paper will give us the most probable value of the I-index (with an associated small standard deviation which decreases with increasing h-index). I show that the total citations (N-c), the h-index and the I-index are three independent parameters (within their bounds), and together they give a comprehensive idea of an author s overall research performance.
