Post-starburst galaxies, also known as k+a galaxies, show no sign of emission lines and prominent Balmer absorption lines in their spectra. They are in a transitional phase between the star forming and the passive galaxies. I present here the study of a sample of eight post-starburst galaxies, belonging to five different galaxy clusters, from the GAs Stripping Phenomena with MUSE (Multi Unit Spectroscopic Explorer at the Very Large Telescope) project dataset. The data-cubes from MUSE had been analyzed in order to study their main properties. In particular the 2D maps of H$\beta$ equivalent width (EW), the star formation history and the specific angular momentum had been argued. These properties had been finally discussed and connected to their environment and morphology.
