Summary
An extreme-relativistic representation is obtained for spin 0 and 1 particles described by the Kemmer equation. Observables characteristic of these particles in this representation are derived.
Riassunto
Si ottiene una rappresentazione relativistica estrema per le particelle con spin 0 ed 1 descritte dall’equazione di Kemmer. Si deducono le caratteristiche osservabili di queste particelle in tale rappresentazione.

In a recent communication, to be published,Strocchi has obtained an E-representation for the Sakata-Taketani form (Sci. Pap. I.P.C.R.,38, 1 (1940)) of the Kemmer equation, and he has shown that in the limit of vanishing mass, this representation goes over directly into Maxwell’s equations, despite the fact that the Sakata-Taketani equation itself does not exist in this limit.

The similarity in the position operator was noticed byPryce (Proc. Roy. Soc., A195, 62 (1948)) also, but we note that ourD-position operator in TableI does not have the non-Hermitian term present in Pryce’s formula forα. Incidentally, the above operator differs from the operator given byGarrido andPascual, who have apparently committed some error in calculation. A calculation byBardacki andAcharya (Nuovo Cimento,21, 802 (1961)) which is somewhat similar in spirit to ours, does not yield the correct results in the Kemmer case.
