This paper bridges a historiographical gap in accounts of the prediction and discovery of the positron by combining three ingredients. First, the prediction and discovery of the positron are situated in the broader context of a period of ‘crystallisation’ of a research tradition. Second, the prediction and discovery of the positron are discussed in the context of the ‘authentication’ of the particle. Third, the attitude of the relevant scientists to both prediction and discovery are conceptualised in terms of the idea of ‘perspectives’. It will be argued that by examining the prediction and discovery of the positron in the context of authentication within a period of crystallisation, we can better understand disagreements regarding the positron between relevant scientists (Dirac, Bohr, and Pauli) in the period 1931–34.

通过结合三种成分，本文弥补了正电子的预测和发现方面的史学差距。首先，正电子的预测和发现位于研究传统“结晶”时期的更广泛背景下。其次，在粒子的“认证”中讨论了正电子的预测和发现。第三，根据“观点”的概念来概念化相关科学家对预测和发现的态度。将会争论的是，通过在结晶期内在认证的背景下检查正电子的预测和发现，我们可以更好地理解1931–34年间有关科学家（狄拉克，玻尔和保利）之间关于正电子的分歧。
