  In this paper we calculate various transition probability amplitudes, TPAs,
known as `weak values' for the Schrodinger and Pauli particles. It is shown
that these values are related to the Bohm momentum, the Bohm energy and the
quantum potential in each case. The results for the Schrodinger particle are
obtained in three ways, the standard approach, the Clifford algebra approach of
Hiley and Callaghan, and the Moyal approach. To obtain the results for the
Pauli particle, we combine the Clifford and Moyal algebras into one structure.
The consequences of these results are discussed.
