Cusp-electron emission in proton on argon collisions has been investigated at impact energies 33, 50 and 75 keV. By detecting the electrons in coincidence with the charge-stateanalysed outgoing H+,()projectiles, the process of electron capture to the continuum (ECC), aswell as the process of simultaneous ecc and bound-state capture (transfer ionization, n) wereidentified. The ratios of the yields for cusp-electron production by re and ecc are found todecrease with increasing projectile energies. At the lowest proton energy (33 keV) the measuredTi/ECC ratio is about four times smaller than the corresponding ratio for incident He+measuredin earlier work. Significant is the finding that there exists a cusp associated with Ti events, and, moreover, that this cusp is present for neutral outgoing projectiles.
