Pseudoscalar Interaction in Nuclear Beta Decay

In Chapter I, the statement of the problem considered in this dissertation is given: the investigation of the existence of the pseudo­ scalar interaction by the formulation of the theoretical expressions for the beta longitudinal polarization and the beta spectrum in 0 --> 0 (yes) beta transitions and by a comparison of the existing experimental data with the developed theory.

In Chapter II, we explain the reasons for the incorrectness of the conventional treatment of the pseudoscalar interaction, and then give the correct form of the operator for this interaction.

In Chapter III, using the correct form of the pseudoscalar inter­ action and the conventional form of the axial vector interaction, we develop the beta longitudinal polarization and the beta shape factor formulas for 0-->0 (yes) beta transitions.

In Chapter IV, , we analyze the experimental data on Pr144 (0- --> 0+)

and Ho166 (0- --> 0+) with the formulas of Chapter III, which in these cases are tabulated on pages 104 and 105 respectively.
