Theoretical approaches for investigating nuclear structure with ([ital e],[ital e][prime]), ([pi],[pi][prime]), and ([gamma],[pi]) reactions are presented and applied to study the shell-model description of [sup 10]B. The distorted wave impulse approximation formulated in momentum space is used to calculate the cross sections of ([pi],[pi][prime]) and ([gamma],[pi]) reactions from the [pi][ital N][r arrow][pi][ital N] and [pi][ital N][r arrow][gamma][ital N] off-shell amplitudes which are generated from the model of Nozawa, Blankleider, and Lee[1]. It is found that the nonlocal effects due to [pi][ital N] off-shell dynamics and nucleon Fermi motion are important in predicting ([gamma],[pi]) cross sections. The one-pion-exchange two-body exchange currents are included in ([ital e],[ital e][prime]) calculations. It is shown that the core polarization effects, calculated in a perturbation approach including excitations up to 6[h bar][omega], are essential in obtaining quantitative agreements with the data with no adjustable parameters. The predictions based on the shell model of Cohen and Kurath [2] and Hague and Maripuu [3] are compared in order to illustrate the use of ([ital e],[ital e][prime]), ([pi],[pi][prime]), and ([gamma],[pi]) reactions in distinguishing nuclear structure theories which are almost equivalent in describing static properties in nuclei. Predictions for future ([ital e],[ital e][prime]) and ([gamma],[pi]) experiments are also presented.
