We quantify the stellar rotation of galaxies by computing the R parameter, a proxy for the stellar angular momentum in a sample of 106 intermediate-redshift galaxies (0. 1 of the galaxies are consistent with being regular rotators (RRs), having rotating stellar discs with flat velocity dispersion maps, while have complex velocity maps and can be identified as non-regular rotators in spite of their R values. For the remaining galaxies the classification is uncertain. As we lack galaxies with R < 0. 1 in the sample, we are not able to identify when galaxies lose their angular momentum and become slow rotators within the surveyed environments, area, and redshift range.
