Abstract

The atomic-beam magnetic-resonance method has been used to measure the nuclear spin and hyperfine-structure separations of 64-hour

Y^{90}

. The results are

I = 2

,

a ({}^{2}D_{\frac{3}{2}}) = - 169.749 (7)

Mc/sec,

b ({}^{2}D_{\frac{3}{2}}) = - 21.602 (27)

Mc/sec,

a ({}^{2}D_{\frac{5}{2}}) = - 85.258 (6)

Mc/sec,

b ({}^{2}D_{\frac{5}{2}}) = - 29.716 (38)

Mc/sec. The uncorrected nuclear moments calculated from these measurements are

μ_{I} = - 1.623 (8)

nm,

Q = - 0.155 (3)
