Abstract

A 39

A

MeV

^{38} S

radioactive beam was used with inverse kinematics to measure angular distributions for elastic and inelastic proton scattering from a

{CH}_{2}

target. Optical potential and folding model calculations are compared with the elastic distribution. Using coupled channel calculations, the

β_{2}

value for the

2_{1}^{+}

state is determined to be 0.35±0.04. This value, when compared with the corresponding result from a Coulomb excitation measurement, leads to

M_{n} {/ M}_{p}

=(1.5±0.3)

N / Z,

indicating an isovector contribution to the

2_{1}^{+}

state of

^{38} S .
