Title: NUCLEAR SPINS OF NEUTRON-DEFICIENT POLONIUM ISOTOPES

Abstract

The atomic-beam magnetic resonance method was used to measure the spins of neutron-deficient polonium isotopes with the following results for mass number, half-life, and spin, respectively: 201, 18 m, and 3/2; 202, 43 m, and 0; 203, 12 m, and 5/2; 204, 3.6 h, and 0; 205, 1.8 h, and 5/2; 206, 8.8 d, and 0; 207, 5.7 h, and 5/2; and the atomic g-factor of polonium g/sub j/ = 1.39609 plus or minus 0.00004. There is some uncertainty as to the spin 0 assignments. For very small hfs, the resonance frequencies for spins other than zero are nearly identical to the transition frequency for spin 0. For that reason an upper limit for the magnetic dipole interaction constant was calculated under the assumption that the spin is one. (auth)
