We employ the four-body continuum distorted-wave (CDW-4B) method to compute the {ital total} cross sections for the single electron-capture process H{sup +}+He(1s{sup 2}){r_arrow}H(1s)+He{sup +}(1s) at incident energies ranging from 20 to 20000 keV. The purpose of the present work is twofold: (i) to verify whether the CDW-4B approximation for one-electron transfer is as successful as for double charge exchange in fast proton-helium collisions and (ii) to search for evidence of dynamic electron correlation effects as a function of increased projectile energy. The validity of our findings is critically assessed in comparisons with the available experimental data in the quoted impact energy range. {copyright} {ital 1997} {ital The American Physical Society}
