Abstract
Gravitational pulse waves are defined as step functions at the boundaries. In this setting, linearized Rarita-Schwinger equations are precisely solved in Rosen coordinates. It is found that the gravitino's energy-momentum varies with the sandwich wave's shape. The gravitino's energy density will decrease as it crosses the sandwich wave at the test field level since the background won't change.
