Proposed forms for nuclear momentum distributions are investigated. Calculations of ($p,p^{\prime }$) reactions using those forms are done in a plane-wave impulse approximation at angles where the quasielastic peak is seen and also at back angles. The parameters used are derived from ($e,e^{\prime }$) data, where the nuclear momenta probed overlap with those of the low angle ($p,p^{\prime }$) experiment. Although there is reasonable agreement for the ($p,p^{\prime }$) data at 180°, the inclusion of distortion necessitates a different parameter set to obtain agreement for the quasifree process. We conclude that the ($p,p^{\prime }$) reaction cannot be readily understood with a simple momentum distribution.
