Spin and Nuclear Moments of 245-Day ${Zn}^{65}$ ; Redetermination of the hfs of ${Zn}^{67}$ and $τ ({}^{3}P_{1})$ of Zinc

The hfs of the

(4 s 4 p) {}^{3}P_{1}

state of 245-day

{Zn}^{65}

and of

{Zn}^{67}

has been determined by the optical double-resonance technique. The nuclear spin

I

, and the hfs splittings are:

{Zn}^{65}

I = \frac{5}{2}

ν (\frac{7}{2} - \frac{5}{2}) = 1875.475 (6)

Mc/sec,

ν (\frac{5}{2} - \frac{3}{2}) = 1334.123 (6)

Mc/sec;

{Zn}^{67}

ν (\frac{7}{2} - \frac{5}{2}) = 2111.300 (3)

Mc/sec,

ν (\frac{5}{2} - \frac{3}{2}) = 1551.565 (4)

Mc/sec. The hfs coupling constants, corrected to second order for interaction with the

{}^{3}P_{2}

and

{}^{3}P_{0}

states, are:

{Zn}^{65}

A (65) = + 535.163 (2)

Mc/sec,

B (65) = + 2.870 (5)

Mc/sec;

{Zn}^{67}

A (67) = + 609.086 (2)

Mc/sec,

B (67) = - 18.782 (8)

Mc/sec. If quadrupole shielding effects are neglected, the corresponding moments of

{Zn}^{65}

are:

μ (65) = + 0.7692 (2)

μ_{N}

and

Q (65) = - 0.024 (2) b

. The value given for

μ (65)

includes an estimated correction of 0.09(8)% for the hfs anomaly. The ratio of the
