The well known distorted-wave Born-approximation formula for breakup processes was first simplified by introducing several approximations, all of which are believed justified for strongly absorptive high-energy projectiles. This made the theory very transparent and the ensuing numerical calculations rather easy to perform. This new formula, which was applied earlier with success to the breakup of ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$, is applied in the present work to that of ${}_{}{}^3{}_{}{}^{}\mathrm{He}$, again with success.

NUCLEAR REACTION Distorted-wave Born approximation; breakup reaction of strongly absorptive projectiles; ${}_{}{}^{51}{}_{}{}^{}\mathrm{V}$(${}_{}{}^3{}_{}{}^{}\mathrm{He}$,$\mathrm{dp}$) reaction, calculated $\frac{d^3\sigma }{\mathrm{dE}d\Omega d\Omega }$; $E\left({}_{}{}^3{}_{}{}^{}\mathrm{He}\right)=90\mathrm{}$ MeV.
