Summary
A linearization of the two-component second order spinor equation of Feynman and Gell-Mann for spin one-half particles leads to a ten component equation of the Kemmer type. Up to now such equations were only known for integral spin particles.
Riassunto
Una linearizzazione della equazione spinoriale del secondo ordine a due componenti di Feynman e Gell-Mann per particelle di spin 1/2 porta ad una equazione a dieci componenti del tipo di Kemmer. Sinora queste equazioni erano note solo per particelle a spin intero.
