Abstract

The giant-resonance region was studied for

{}^{40}{Ca}

,

{}^{40}{Ar}

,

{}^{36}{Ar}

,

{}^{32}S

,

{}^{28}{Si}

,

{}^{27}{Al}

,

{}^{20}{Ne}

, and

{}^{16}O

by inelastic scattering of 96.6-MeV

α

particles. A systematic broadening of the isoscalar giant resonance at

E_{exc} ≃ \frac{63}{A^{\frac{1}{3}}}

MeV occurs as

A

decreases. The width for

{}^{40}{Ca}

is 3.5±0.3 MeV, for

{}^{32}S

it is 7.1±0.5 MeV, and for nuclei below

A = 32

the resonance is too diffuse to be observed.
