Touschek agrees with the introduction of a new index in Pauli's theory. He writes about the discrete mass spectrum in the field-free case as function of total isotopic spin.

Touschek gives "weak" and "strong" postulates on reversibility of field operators for a system of observables as used in his work. He writes about S-matrix elements for irreversible system.

Touschek writes about Pais paper published in Physica. He writes about his own work on time-reversal.

Touschek comments a part of Pauli's lecture in Varenna, which is superscribed "The nucleon magnetic moment in the static theory".
