Resonance of the two cadmium isotopes 11, 113 observed & confirmed at 6.17 MC & 5.90 MC for a magnetic field 6600 gauss

RESONANCE FREQUENCIES

Cd A (Marker 6200 KC --> 6175 KC)

[Greek letter mu] CdA = 0.623 + 0.001 [Greek letter mu] CdB = 0.595 + 0.001

[Greek letter mu] CdA = 1.0461 + 0.0001 [Greek letter mu] CdB

The sign of the magnetic moments of Cd isotopes was compared with that of iodine & sodium. It showed that Cd isotopes have negative magnetic moments

Resonance Frequencies [double underline] Sn^115 (6250 -> 6225 KC)

Na^23 (5050 -> 5025)

V ( Sn 115 ) = 6236.4 ( 1 + 5X10-5 )

V ( Na 23 ) = 5044.6 ( 1+ 4X10-5 )

V ( Sn 115 ) = 6236.4 ( 1+ 6.2 x 10-5 ) V ( Na 23 ) = 5044.6

= 1.23625 ( 1+ 6.2 x10 -5 ) = 1.23625 (1+0.00006 ) = 1.23625 + 0.000076

Data obtained by WP

V (Sn 119 ) = 1.4090 + 0.0005 V ( Na 23 )

V ( Sn 117 ) = 1.3464 + 0.0004 V ( Na 23 )

V ( Sn 119 ) = 1.0465 + 0.0003 V ( Sn 119 )

M ( Sn 117 ) = - 1.0000 + 0.0009 MN M (Sn 119 ) = - 1.0466 + 0.0009 MN
