0:00:04the work summarised in the present video abstract was performed and the don't know international
0:00:11phonetic centre or g i p c in something that can spain
0:00:16the d i p c centre was created in two thousand by professor pedro h
0:00:22and u k
0:00:23we among other aims
0:00:25two zero is an international platform from basic science in the basque country
0:00:31in the field of material time
0:00:35professor pedro action tk if the condensed matter theories serving as current director of the
0:00:42g i p
0:00:43he's an expert on the interactions of charged particles with matter
0:00:48and he's one of the four core orders of the paper the other three co
0:00:53authors are also condensed matter a theories professor are more local from them you bellingham
0:01:00my and soon units from zagreb croatia and georgia then iterate from milan though it
0:01:06is over the last two years while visiting the g i p c
0:01:11the scientists have worked on the variety of research project including the present work
0:01:19they're in here relaxing at like contain something about down after have this work in
0:01:24the centre
0:01:25they are grateful to professor pedro a chain again for creating and maintaining the high
0:01:31stimulating intellectual environment of the d i p c
0:01:36and for inviting them to join it's program of visitors
0:01:41onlookers will now present a summary of the work
0:01:48i would like to present
0:01:50that is really abstract by using a tied to which is slightly different from the
0:01:56one used in the printed paper
0:01:59i will use the more evocative dido

0:02:51the irony sex evaluated by gaining the potential energy loss by the transferred electron
0:03:00the transfer calls is a plus one tsunami on the model q
0:03:05when it's remaining electrons a harsh to screen the whole

0:03:14the plus one excitation energy is extracted from the i am kinetic energy gain
0:03:22they're q plus a and is passionately neutralize to q minus s plus
0:03:28where s maybe one or more
0:03:33a spectrometer select
0:03:36the q minus one plus or q minus two plus ions
0:03:41for energy analysis
0:03:44and produces energy getting spectra for the two kinds of idea
0:03:52the spectrum of the queue minus one process only on
0:03:56begin with sharp peaks
0:03:59and and's with the wrong oscillatory table
0:04:04the spectrum of the queue minus two plus a and
0:04:08has a bell shape
0:04:10and many oscillations on top
0:04:14the period of oscillations in both spectra is exact on vowel
0:04:20which coincides with the quantum of bypass models in c sixty
0:04:27the present paper develops a quantum theory
0:04:31which quantitatively explains the spectra reported by sellable work at all
0:04:37in physical review a fifty three
0:04:40of nineteen ninety six
0:04:43here is the comparison between theory and experiment
0:04:48for the q equal fifteen spectra
0:04:52it is clear that the theoretical model captures the essential physics of the complex process
0:05:01the experimental method and the present theory a promising to
0:05:06to explore in elastic charge transfer processes in this and correlations between the highly charged
0:05:12ions
0:05:14and a variety of the molecule also target
