✦ Synopsis

distinctive r.f. radiation events.

In five instances, however, no effect is observed to accompany major chromospheric eruptions.

The results cannot be accounted for solely on the basis of the expected impact zones for charged particles originating at the sun. Efforts are in progress to determine whether some recognizable fundamental differences between the two groups of flares exist.

With gaseous sources of Se76 in the form of selenium oxide, resonance scattering from the 265 kev leve1 in As'~ has been observed.' Preliminary measurements indicate an isotopie distribution of the resonance radiation and thus favor assignment of spin 1/2 to the 265 kev leve1 in As'~. Self-absorpti

Using a source of As v4 in the form of arsine gas, a resonance fluorescence effect from the 635 kev level in Se v4 has been observed. Due to the small abundance of Se v4 (0.87 per cent), the effect is not very pronounced and the mean life of 6 X 10 -12 second, calculated from the magnitude of the re
