Abstract

Neutron spectra from

{}^{90}{Zr} (p, n) {}^{90}{Nb}

at

E_{p} = 120

MeV are measured in the angular range 0°-25°. Three giant resonances are seen and are interpreted as the

T = 4

and

T = 5

components of the Gamow-Teller strength and an

E 1

resonance. Gamow-Teller matrix elements are extracted, and a large part of the expected strength is found.
