<br>
Could anyone clarify to us the situation with the toxicity of
Copper: what ratio of (Cu-63 + Cu-65) to Cu-67 atoms in the final
product is too big, such that the product would become
unacceptable.<br>
<br>
We understand now that by making Cu-67 from Gallium, for example,
the ratio could be done less than an order of few times, or even
less than one. In case of Zinc target the ratio would be worse
because the stable isotopes of Zinc are closer in both Z and A to
stable Cu-63 and Cu-65 than the isotopes of Gallium. I guess this
ratio would be enormous if Cu-67 is produced in Copper with double
neutron captures on reactors.<br>
<br>
In our conditions, without the initial Copper in the target, the
ratio should stay rather limited, with the Gallium target having
some advantage in that respect. Would that be good enough? What
would be a hard limit on the ratio?<br>
<br>
Best regards,<br>
Pavel<br>

<div>I wonder if, in the meantime - before the phone call is
held, VCU can share with us the list of nuclear species
that they are interested in? We (SDSM&T) could look
into photo-production of them if we knew what species are
on their mind.<br>

Dear George and All,<br>
<br>
I regret to inform you that due to an emergency in Dr.
Zweit's family, he will not be able to come and present
his ideas at JLab today.
<br>
<br>
Once he returns to work, he will get in touch with you to
reschedule his presentation.<br>
<br>
Very sorry about any inconvenience this may cause.<br>
<br>
Best regards,<br>
Sundaresan<br>
