-Spectra that are obtained from a [[sector mass spectrometer]] that incorporates at least one [[magnetic sector]] plus one [[electric sector]] in [[reverse geometry]]. The accelerating voltage, V, and the [[magnetic sector]] field, B,  are set at fixed values to select the precursor ions, which are then allowed to dissociate or to react in a [[field free region]] between the two sectors. The kinetic energy [[product ion]]s of ''[[m/z]]'' selected [[precursor ion]]s is analyzed by scanning the [[electric sector]] field, E. The width of the [[product ion]] spectrum peaks is related to the [[kinetic energy release distribution]] ([[KERD]]) for the dissociation process.
+A procedure by which mass spectra are obtained from a [[sector mass spectrometer]] that incorporates at least one [[magnetic sector]] plus one [[electric sector]] in reverse geometry. The accelerating voltage, V, and the magnetic flux density, B, are set at fixed values to ''[[m/z]]'' select the [[precursor ion]]s, which are then allowed to dissociate or to react in a [[field-free region]] between the two sectors. The translational kinetic energy-to-charge ratios of the various product ions are analyzed by scanning the electric sector field E. The width of the product ion spectrum peaks is related to the kinetic energy release distribution for the dissociation process.
+The term [[direct analysis of daughter ions]] ([[DADI]]) is deprecated.
