Hi All

Apologies that this has been sent a bit late.

The journal to be discussed this week is 'Modeling multi-nucleon transfer
in symmetric collisions of massive nuclei'
(http://www.sciencedirect.com/science/article/pii/S0370269317304070).
Questions are below:

1) The grazing model predictions for asymmetric reactions 'agree well'
with experimental measurements and fail to describe symmetric reactions.
Asymmetric reactions have fewer valance nucleons than symmetric reactions
(for the cases presented here) so is failure to describe symmetric
reactions a result of the increased number of valance particles?

2) Without measuring the scattered particles, can we be certain that these
are these really multi-nucleon transfer reactions? Could the reaction
products be made in a different reaction mechanism.

3) Why wait 22 hours after irradiation to measure the gamma rays? If the
source activity is too high to measure right after irradiation why not
move the detector further away to allow the shorter lived reaction
products to be measured?

4) The tef (theory evaluation factors) for reactions involving only
neutron transfer (ΔZ=0) show good agreement with experimental data. Why
might the models describe neutron transfer well and not proton transfer?
Is it simply a charge effect?

More questions may appear later if I can think of any. As usual, we'll
meet on Wednesday at 3:30 in the MOB Theory Room.

See you all there.
