Abstract

A study has been made of the breakup of 70-MeV

{}^{7}{Li}

into the

α + t

channel. For reactions on a

{}^{12}C

target the

{}^{7}{Li}

breakup proceeds sequentially through its 4.63-MeV,

{\frac{7}{2}}^{-}

state. For reactions on a

{}^{208}{Pb}

target, there is evidence both for sequential breakup and for an additional breakup process which does not proceed through an excited state of

{}^{7}{Li}

. This latter process is attributed to direct projectile breakup in the nuclear field of the target.
