Abstract

The isotopes

{Dy}^{155}

and

{Dy}^{157}

were aligned at low temperatures in a single crystal of neodymium ethylsulfate, using the magnetic hfs method. Angular distribution of gamma radiation following the decay of these isotopes was studied as a function of temperature in the region

0.02 ° K < T < 1 ° K

. Spin assignments of

\frac{5}{2} -

were made to states at 227 kev in

{Tb}^{155}

and at 327 kev in

{Tb}^{157}

. Assuming

I = \frac{3}{2}

for both dypsprosium isotopes as well as pure

L = 1

beta decay to the

\frac{5}{2} -

states, nuclear moments of

| μ_{155} | = 0.21 \pm .05

nm and

| μ_{157} | = 0.32 \pm 0.02

nm were derived.
