N2 - Partial ionization cross section (PICS) measurements of the cations created through electron impact in the energy range from threshold ionization to 100 eV have been undertaken for 38 cations of 2-butanol, using a HIDEN quadrupole mass spectrometer (EPIC 300) with a mass resolution of 1 amu. These PICSs, which are being presented here for the first time, correspond to the cationic fragments with the highest intensity signal registered in our 2-butanol mass spectrum reported previously (Amorim et al. in Eur J Phys D 76:207, 2022). Experimental and theoretical total ionization cross sections (TICSs) for the electron impact of 2-butanol are also reported here, where the agreement between measured and calculated TICS over their common energy regimes was, allowing for the measurement uncertainties, typically quite good. Based on the previously reported appearance energy values and the PICSs profiles reported here, we propose some ionic fragmentation mechanisms for this molecule.
