> Dear Tom, Mark, Tim and Flemming:
>
> In one week's time, the PHENIX Collaboration plans to submit a manuscript
to
> Physical Review C describing systematic features of charged multiplicity
and
> transverse energy at 19, 130 and 200 GeV in Au+Au collisions. The title
and
> abstract are included below.

> The PHENIX experiment at RHIC has measured transverse energy and charged
> particle multiplicity
> at mid-rapidity in Au+Au collisions at $B"e(BsNN = 19.6, 130 and 200 GeV as a
> function of
> centrality. The presented results are compared to measurements from other
> RHIC experiments, and
> experiments at lower energies. The $B"e(BsNN dependence of dET /d$B&G(B and
dNch/d$B&G(B
> per pair of participants
> is consistent with logarithmic scaling for the most central events. The
> centrality dependence
> of dET /d$B&G(B and dNch/d$B&G(B is similar at all measured incident energies. At
> RHIC energies the ratio of
> transverse energy per charged particle was found independent of centrality
> and growing slowly with
> $B"e(BsNN . A survey of comparisons between the data and available theoretical
> models is also presented.
