Abstract:

The α-decay energy and halflife of 195mAt were determined to be 6960±20 keV and 385+69 −51 ms respectively, on the basis of genetic correlations in the 169Tm(36Ar, α6n)195At reaction, while those of 195gAt measured simultaneously were 7105±30 keV and 146+21 −17 ms respectively, reconfirming the previously reported values. A new isotope 199Fr was also produced and identified in the same way in the 169Tm(36Ar, 6n)199Fr reaction, yielding Eα= 7655±40 keV and T1/2= 12+10 −4 ms.
